Health Promotion in schools,

the workplace and the

community





Health Psychology

Schools

Walter et al., 1985

 Some school programs have been

effective. An experiment in 22

elementary schools introduced a

carefully designed curriculum with

emphasis on nutrition and physical

fitness (Walter et al., 1985). The

schools were randomly assigned so that

their students either participated in the

program or served as a control group.

Walter et al., 1985

 The researchers compared the two

groups after a year. Relative to the

control subjects, the children who

participated in the program showed

improvements in their blood pressure

and cholesterol levels.

Edwards and Hartwell (2002)

 Edwards and Hartwell (2002)

investigated whether children, aged 8-

11 years could correctly identify

commonly available fruit and

vegetables; to assess the acceptability

of these; and to gain a broad

understanding of children's perceptions

of 'healthy eating'. Fruit and vegetables

used were those readily available in

retail outlets in the UK.

Edwards and Hartwell (2002)

 Data were collected from 221 children

using a questionnaire supported by

semistructured interviews and

discussions. Overall, fruit was more

popular than vegetables and recognition

of fruit better; melons being the least

well identified.

Edwards and Hartwell (2002)

 Recognition of vegetables increased

with age; the least well identified being

cabbage which was confused with

lettuce by 32, 16 and 17% of pupils in

their respective age groups. Most

children (75%) were familiar with the

term healthy eating, citing school

(46%) as the most common source of

information.

Edwards and Hartwell (2002)

 Pupils showed an awareness and

understanding of current

recommendations for a balanced diet,

although the message has become

confused. If fresh fruit and vegetables

are to form part of a balanced diet, the

'health message' needs to be clear.

Edwards and Hartwell (2002)

 Fruit is well liked; vegetables are less

acceptable with many being poorly

recognized, factors which need to be

addressed.

Parcel, Bruhn, & Cerreto, 1986

 Another study found that more children

practiced safety behaviour if they were

taught about health and safety in a 4-

year program than if they were not

(Parcel, Bruhn, & Cerreto, 1986).

Kolbe & Iverson, 1984

 But many schools do not provide health

education at all, or their programs are

under funded, poorly designed, and

taught by teachers whose interests and

training are in other areas (Kolbe &

Iverson, 1984).

Coates et al. (1985)

 Coates et al. (1985) examined the

effectiveness of a 4-week school-based

intervention for decreasing consumption

of salty snack foods and increasing

consumption of ―heart healthy‖ snacks

among African American adolescents.

Coates et al. (1985)

 One hundred fifty-four students from

one high school received the treatment

program, whereas 130 students from

another high school served as the no-

treatment control group. The program

incorporated parental involvement, a

school wide media program, and a

classroom instruction program.

Coates et al. (1985)

 The classroom instruction program

included setting written goals for

substituting heart-healthy snacks for

salty snacks. The treatment program

was effective in producing reductions in

salty snack foods, however, long-term

changes were only significant for

students who participated in the

classroom instruction program that

incorporated written objectives.

Bush et al. (1989)

 Relatedly, Bush et al. (1989) examined

the effects of a 4-year program for

reducing coronary heart disease risk

factors among 1,041 African American

adolescents. Participants were randomly

assigned to either a treatment program

or a control program (no treatment).

Bush et al. (1989)

 The treatment program involved goal

setting, modelling, rehearsal, feedback

of screening results, and reinforcement

of healthful eating behaviours.

Treatment participants showed

significant decreases in cholesterol and

blood pressure, which were maintained

over a 2-year follow-up.

Perry et al. (1989)

 In Perry et al‘s (1989) study, younger

children (ages 8—9 years) participated

in either a treatment or control school-

based program designed to increase

healthy eating habits. The intervention

program included modelling through

stories and role-playing, self-monitoring

of behaviours, behavioural contracting,

and material rewards.

Perry et al. (1989)

 Treatment participants showed

significant reductions in the use of salt.

Together, these studies reviewed above

provide evidence that incorporating

directly observable behavioural

objectives—such as setting written

goals, modelling behaviours, and

providing feedback—can successfully

result in long-term dietary change.

Staff support

 Another important aspect of school-

based interventions has been obtaining

support from school staff (e.g.,

teachers) and school cafeteria

providers.

Staff support

 Bush et al. (1989) reported that young

African American adolescents who were

part of a coronary heart disease

prevention program and were judged to

have the best teachers showed

significant decreases in total serum

cholesterol at a 2-year follow-up.

Staff support

 Resnicow, Cross, and Wynder (1991)

also examined the effects of a

comprehensive school health education

program designed to decrease total

cholesterol in young adolescents. They

conducted three studies with a

combined sample of Whites, African

Americans, and Hispanics.

Staff support

 The program incorporated a teacher

component, a health-screening

component, and extracurricular

activities. The teacher component

advocated decision-making, goal

setting, and communication skills. The

extracurricular activities included

modifying the school cafeteria,

developing recipe books, and holding

heart-healthy bake sales.

Staff support

 The intervention schools reported

significantly less consumption of high-

fat foods in comparison with no-

treatment schools. The intervention

participants also showed 4%—7%

decreases in total cholesterol level

across all ethnic groups.

Staff support

 Although Bush et al. and Resnicow et

al. did not specifically determine which

components of their programs were

most effective in creating dietary

change, their findings do provide

evidence for the importance of

obtaining support from school staff and

cafeteria providers when designing

dietary interventions for adolescents.

Healthier food options

 Other investigators have more

specifically modified school cafeteria

programs to provide healthier food

options. Parcel, Simons-Morton, O‘Hara,

Baranowski, and Wilson (1989) worked

with the food service personnel to

institute specific goals for dietary

change in several school cafeterias in

Houston, Texas.

Healthier food options

 Their study sample was 62% White,

2I% Mexican, 15% African American,

and 2% Asian American and Native

American. Participants ranged in age

from 5 to 10 years.

Healthier food options

 School lunches were modified to

decrease the sodium content to less

than 600 mg per average school lunch

and to decrease the total fat to 30%

and saturated fat to 100% or less of the

total calories per day. New recipes were

tested for taste, texture, appearance,

and appeal. The results demonstrated

significant decreases in the use of salt.

Healthier food options

 Similarly, in a recent review by Stevens

and Davis (1988) it was found that

effective dietary programs modified the

offerings of school cafeterias to include

salad bars, fresh fruit, and whole grain

breads. Continued research is needed

to better understand how programs

such as these might affect specific

adolescent minority groups.

 French et al (2001)

examined the effects

Pricing of pricing and

promotion strategies

on purchases of low-

fat snacks from

vending machines.

Low-fat snacks were

added to 55 vending

machines in a

convenience sample

of 12 secondary

schools and 12

worksites.

Pricing

 Four pricing levels (equal price, 10%

reduction, 25% reduction, 50%

reduction) and 3 promotional conditions

(none, low-fat label, low-fat label plus

promotional sign) were crossed in a

Latin square design. Sales of low-fat

vending snacks were measured

continuously for the 12-month

intervention.

Pricing

 Results show that price reductions of

10%, 25%, and 50% on low-fat snacks

were associated with significant

increases in low-fat snack sales;

percentages of low-fat snack sales

increased by 9%, 39%, and 93%,

respectively. Promotional signage was

independently but weakly associated

with increases in low-fat snack sales.

Pricing

 Average profits per machine were not

affected by the vending interventions. It

is concluded that reducing relative

prices on low-fat snacks was effective in

promoting lower-fat snack purchases

from vending machines used by both

adult and adolescent populations.

Culturally relevant information

 More recently, investigators have

integrated culturally relevant

information into their school-based

dietary interventions. For example,

Schinke, Moncher, and Singer (1994)

developed a cancer risk-reduction

program that included a nutrition focus

on reducing fat intake and increasing

such nutrients as fibre and carotene.

Culturally relevant information

 The study included 368 Native

American adolescents whose schools

participated in either an intervention or

a control program.

Culturally relevant information

 The intervention involved using an

interactive computer program to

present information in the context of a

Native American story. The story

emphasised the culturally relevant

traditional advantages of sound

nutrition (e.g., natural and whole

foods).

Culturally relevant information

 A second aspect of the computer

program focused on problem solving

and helping adolescents to offset

negative pressures within the context of

the story. ‗The students received

positive feedback on what they had

learned through a computerised post-

test.

Culturally relevant information

 Students in the intervention program

showed a greater increase in knowledge

regarding positive dietary changes than

students from schools who did not

receive the intervention. This study did

not include behavioural measures to

determine if this acquired knowledge

would generalise to adolescents‘

behaviour.

Culturally relevant information

 Nevertheless, this type of program may

be especially effective with minority

adolescents because it is culturally and

developmentally appropriate and has a

game like quality.

Aerobic exercise

 Ewart, Loftus and Hagberg (1995)

evaluated the efficacy of school-based

aerobic exercise program for lowering

blood pressure in a high-risk urban

sample of ninth-grade African American

girls. Girls in the intervention group

received a one-term aerobics class of

fitness instruction and training designed

to be enjoyable and engaging for high-

risk girls.

Aerobic exercise

 Eighteen 50-min class periods involved

lecture and discussion and 60 class

periods were spent performing aerobic

exercise. Girls assigned randomly to the

control group just received the regular

PE curriculum. After completing the

course 81% wished to continue for

another term, demonstrating their

enjoyment and a developing

commitment to regular exercise.

Peer-based programmes

 We prefer to take advice from people

like ourselves or from people who we

respect. It seems reasonable to

suggest, then, that health education

programmes led by your peers will be

more successful than programmes led

by adult strangers or by teachers.

Peer-based programmes

 Bachman et al. (1988) looked at a

health promotion programme where

students were asked to talk about drugs

to each other, to state their disapproval

of drugs and to say that they didn‘t take

drugs. The idea was to create a social

norm that was against drug taking and

also give people practice in saying ‗no‘.

Peer-based programmes

 It was claimed that the programme

changed attitudes towards drugs and

led to a reduction in cannabis use. A

similar programme was reported by

Sussman et al. (1995) who compared

the effectiveness of teacher-led lessons

with lessons that required student

participation. The study looked at

around 1000 students from schools in

the US.

Peer-based programmes

 Results suggested that there were

significant changes in attitudes to drugs

and intentions to use drugs in the active

participation lessons, but not in the

teacher-led lessons.

WORKSITE WELLNESS

PROGRAMS

Health hazard appraisal

 An example of a work-based health

programme was introduced at a glass

product company in Santa Rosa,

California (Rodnick, 1982, cited in

Feuerstein, 1986, p. 271). A ‗health

hazard appraisal‘ counselling session

was carried out with nearly 300

employees at the company.

Health hazard appraisal

 As part of the programme, full-time

staff were offered a comprehensive

health examination which included:

 • health history

 • weight and height measurement

 • blood pressure measurement

 • range of blood tests including: cholesterol, liver

enzyme level, calcium, protein etc.

 • TB skin test

 • stool test

 • physical examination.

Health hazard appraisal

 This information was used to provide

feedback on the risks of contracting

various diseases including specific

cancers and cardiovascular disease.

About two weeks after the tests, the

workers attended a group session

where they received feedback about

their health-risk profiles. They were also

given information about hypertension,

heart disease and cancer.

Health hazard appraisal

 One year later the workers were tested

again and the following improvements

in their general health were observed:

– • decrease in blood pressure (particularly in

individuals with mild hypertension)

– • reduction in cholesterol levels in men

– • decrease in cigarette smoking

– • increase in exercise

– • increase in breast self-examination (BSE)

– • decrease in alcohol consumption in men

– • increase in seat-belt use by men.

Health hazard appraisal

 A survey of over 1,300 worksites with

50 or more employees found that nearly

two-thirds offered some form of health

promotion activity, such as for fitness

and weight control (Fielding &

Piserchia, 1989). Some programs award

prizes for losing weight, or pay

employees for stopping smoking, or

give bonuses for staying well.

Health hazard appraisal

 By doing this, employers are helping

their workers and saving a great deal of

money. Workers with poor health habits

cost employers substantially more in

health benefits and other costs of

absenteeism than those with good

habits. These savings offset and often

exceed the expense of running a

wellness program (Winett, King, &

Altman, 1989).

Health hazard appraisal

 Worksite wellness programs vary in

their aims, but they usually address

some or all of the following risk factors:

hypertension, cigarette smoking,

unhealthy diets and overweight, poor

physical fitness, alcohol abuse, and high

levels of stress. Housing these

programs in workplaces has several

advantages:

Health hazard appraisal

 · (a) Most employees go to the

workplace on a regular schedule,

facilitating regular participation in the

programs;

 · (b) contact with co-workers can

provide reinforcing social support

Health hazard appraisal

 · (c) the workplace offers many

opportunities for environmental

supports, such as healthy food in the

cafeteria and office policies regarding

smoking;

 · (d) opportunities abound for positive

reinforcement for individuals

participating in the programs;

Health hazard appraisal

 · (e) programs in the workplace are

generally less expensive for the

employee

 · (f) programs in the workplace are

convenient. (Cohen, 1985, p. 215).

 Unfortunately, the employees who do

not participate are often the ones who

need it most - those who report having

poor health and fitness (Alexy, 1991).

Johnson & Johnson's "Live

for Life" Program

 Johnson & Johnson is America's largest

producer of health care products. They began

the Live for Life program in 1978, and it is

one of the largest, best funded, and most

effective worksite programs yet developed

(Fielding, 1990; Nathan, 1984). The number

of employees covered by the program has

grown over the years and now exceeds

31,000.

Johnson & Johnson's "Live

for Life" Program

 The health goal of the program is to

help as many employees as possible live

healthier lives by making improvements

in their health knowledge, stress

management, and efforts to exercise,

stop smoking, and control their weight.

Johnson & Johnson's "Live

for Life" Program

 For each participating employee, Live for Life

begins with a health screen - a detailed

assessment of the person's current health

and health-related behaviour, which is shared

with the individual later. After taking part in a

lifestyle seminar, the employee joins action

groups for specific areas of improvement,

such as quitting smoking or controlling

weight. Professionals lead sessions of these

action groups, focusing on how the

employees can alter their lifestyles and

maintain these improvements permanently.

Johnson & Johnson's "Live

for Life" Program

 Follow-up contacts are made with each

participant during the subsequent year.

The company also provides a work

environment that supports and

encourages healthful behaviour: it has

designated no-smoking areas,

established exercise facilities, and made

nutritious foods available in the

cafeteria, for example.

Johnson & Johnson's "Live

for Life" Program

 All the employees studied completed a health

screen in the initial year and then again in

later years. Compared with the employees at

the companies where Live for Life was not

offered, those where it was have shown

greater improvements in their physical

activity, weight, smoking behaviour, ability to

handle job stress, absenteeism, and hospital

medical claims.

Control Data's "StayWell"

Program

 Each StayWell participant completes a health

screening, receives a resulting confidential

health risk profile, and attends a workshop

that focuses on interpreting the profile. The

person can then join courses taught by

professionals that provide information about

lifestyle and health and teach the skills

needed to change unhealthful behaviors.

There are courses in physical fitness,

nutrition, weight control, stopping smoking,

and stress management.

Control Data's "StayWell"

Program

 The individual can also join action teams that

focus on two things:

(1) making the work environment more healthful,

(2) forming support groups whereby members

help one another in changing their behaviour.

 Evaluation of the StayWell program uses two

approaches.

1. Some sites did not offer the Staywell program,

and therefore could be used as controls.

2. Employess exhibited varying degrees of

participation in the Staywell program so

comparisons could be made.

Smoking reduction

 An attempt to encourage people to quit

smoking was carried out at five worksites. All

the sites received a six-week programme in

cognitive behaviour therapy which focused on

the skills of giving up. The workers who

enrolled in the programmes in four of the

sites were put into competing teams, with the

workers at the fifth site acting as a control. At

the end of the programme 31 per cent of the

people in the programme at the control site

and 22 per cent at the competition sites had

stopped smoking.

Smoking reduction

 A follow-up study after six months found that

18 per cent of the control group and 14 per

cent of the competition groups had stayed off

the cigarettes. This appears to suggest that

the control group were doing better than the

competition groups, but this was not the

case. At the competition sites 88 per cent of

the smokers joined the programme, but only

54 per cent did so at the control site,

suggesting that the incentive of competition

encouraged more people to attempt to give

up.

Smoking reduction

 When the data was compared for the

total number of smokers at each site to

give up, there was an overall reduction

of 16 per cent at the competition sites

and only 7 per cent at the control site

(Klesger et al. 1986).

Smoking reduction

 A worksite intervention that has grown

in popularity is to ban smoking at work.

One of the questions to consider about

this policy is whether smokers reduce

their consumption because of the ban,

or whether they simply adjust their

behaviour and smoke at different times.

Smoking reduction

 A smoking ban in Australian ambulance

crews was monitored by self-report

measures, and also by physiological

measures such as blood and exhaled

carbon dioxide. The measures were

taken just before the ban, just after it,

and again six weeks later.

Smoking reduction

 The self-report results showed that the

ambulance crews reported less smoking

both at the start of the ban and after

six weeks. The physiological measures,

however, returned to the baseline

measures after six weeks, suggesting

that the smokers were finding other

times to smoke, or were maybe finding

secret places to smoke while at work

(Gomel et al., 1993).

Smoking reduction

 This suggests that worksite smoking

bans might well be useful in changing

behaviour at work, and also improving

the quality of life for non-smokers, but

their overall effectiveness in reducing

smoking is far less clear.

Smoking reduction

 The problem of measuring the effectiveness

of worksite health promotion is a general one

that goes beyond ‗quit smoking‘ programmes.

A review of over 100 programmes of worksite

health promotion found that only a quarter of

them were initiated in response to the needs

or views of the workers, and very few

involved partnerships between workers and

employers.

Smoking reduction

 Most of the programmes were aimed at

changing individual behaviour and did

not include any changes in the working

environment or working practices to

encourage these behaviours. The

review also noticed a gap between what

was regarded as ‗good practice‘ and

what has been found to be effective in

research studies (Harden, et al., 1999).

Smoking reduction

 I guess this means that, as with many

other health interventions, people do

what they believe to be the right thing,

rather than what research has told us is

the best thing.

Smoking reduction

 However, health promotion at the

workplace has been successful in

reducing absenteeism, health insurance

claims and in improving health

behaviours in weight control, exercise,

smoking, nutrition, and stress

management (Jose & Anderson, 1990;

Naditch, 1984).

COMMUNITIES



 Coronary heart Disease and mass

media appeals

– It is difficult to evaluate the effect of mass

media appeals. In the case of product

advertising the effect can be measured in

sales. In the case of health behaviour it is

difficult to come up with appropriate

measures since there are so many

influences on us every day.

Coronary heart Disease

and mass media appeals

 One of the most famous studies on the

effectiveness of mass media messages

was the Stanford Heart Disease

Prevention Programme (see, for

example Farquhar et al., 1977). This

study looked at three similar small

towns in the US.

Coronary heart Disease

and mass media appeals

 Two of the towns received a massive

media campaign concerning smoking,

diet and exercise over a two-year

period. This campaign used television,

radio, newspapers, posters and

mailshots. The third town had no

campaign and so acted as a control.

Coronary heart Disease

and mass media appeals

 The researchers interviewed several

hundred people in the three towns

between the ages of 35 and 60. They

were interviewed before the campaign

began, after one year, and again after

two years when the campaign ended.

Coronary heart Disease

and mass media appeals

 The interviews included questions about

health behaviours, knowledge about the

risks of heart disease, and physical

measures such as blood pressure and

cholesterol levels. In one of the two

campaign towns, the researchers used

the interview data to identify over one

hundred people who were at high risk

of heart disease and offered them one-

to-one counselling.

Coronary heart Disease

and mass media appeals

 The people in the control town showed

a slight increase in risk factors for heart

disease, and the people in the

campaign towns showed a moderate

decrease. The campaign produced

increased awareness of the dangers of

heart disease but produced relatively

little change in behaviour.

Coronary heart Disease

and mass media appeals

 The exception to this was the people

who had been offered one-to-one

counselling — this group showed

significant changes in behaviour. This

study suggests that mass media

campaigns by themselves produce only

small changes in behaviour, but they

can act as a cue to positive action if

further encouragement is offered.

Reducing skin cancer risk

Reducing skin cancer risk

Reducing skin cancer risk

 Over the past twenty years there has

been a large growth in the incidence of

skin cancers, which might be due to a

combination of changes in the

environment and changes in lifestyles.

There are a number of health

promotion campaigns to encourage safe

behaviours in the sun.

Reducing skin cancer risk

 A study on the effectiveness of these

programmes was carried out by

McClendon and Prentice (2001). White

students who chose to tan were given a

health promotion intervention based on

protection motivation theory (PMT).

Reducing skin cancer risk

 The intervention was made up of brief

lectures, an essay, short discussions

and a video about a young man who

died of melanoma (a particularly

dangerous form of skin cancer). There

were two sessions, each just over one

hour long and taking place two days

apart.

Reducing skin cancer risk

 The researchers used psychometric

tests to estimate responses to a range

of variables including:

– • vulnerability

– • severity of the threat

– • self-efficacy

– • costs and rewards

– • intentions.

Reducing skin cancer risk

 With the exception of self-efficacy,

these variables all showed some

significant change after the intervention

and remained effective one month later.

However, the issue is not whether

people intend to change their

behaviour, but whether they actually do

change their behaviour. This is always

more difficult to measure.

Reducing skin cancer risk

 In this study, however, they took

photographs of the participants at the

start of the study and again after one

month. These pairs of photographs

were then judged by four blind-raters

(judges who did not know whether the

pictures were before or after) to see

whether the students‘ skin had tanned

further or become lighter.

Reducing skin cancer risk

 The students were not aware that this

judgement would take place. Of the 32

individuals photographed, 23 (72 per

cent) were judged to have lighter skin

tone after one month, 4 (12.5 per cent)

were rated as having no change and 5

(16 per cent) were judged to have

darker skin.

Homelessness

 Not everybody has equal access to

healthcare. Some members of our

society are socially excluded from the

wealth and health that most people

enjoy. One group of people who fall

into this category is the homeless, and

one of the challenges for health

promotion is to create initiatives that

deal with their needs.

Homelessness

 The health status of homeless people is

very poor compared to the general

population (Plearce and Quilgares,

1996). This is true for diet, malnutrition,

substance misuse, mental health

problems, infectious diseases such as

tuberculosis), cardiovascular disease,

accidents and hypothermia.

Homelessness

 Homeless people commonly come to

the attention of health workers only

when they develop an illness rather

than through screening procedures, and

they often use accident and emergency

departments to deal with their health

problems (Power et al., 1999). As a

result the regular health promotion

programmes often miss them.

Homelessness

 There are a number of barriers to

health promotion for homeless people

including (Power et al., 1999):

 • workers with homeless people are

often isolated and there is not very

much collaboration between the various

agencies that work with the homeless

Homelessness

 • health promotion units do not set up

many initiatives aimed specifically at

homelessness and housing

 • homeless people can feel alienated

from health education messages as

they often require a high level of

literacy

Homelessness

 although homeless people are

concerned about health problems,

issues such as low self-esteem and low

expectations can prevent them from

taking part in heath promoting

activities.
