Unsafe sexual behaviour in South African youth

A growing body of evidence points to the complexity of sexual behaviour. HIV risk behaviour is influenced by factors at three levels: within the person, within the proximal context (interpersonal relationships and physical and organisational environment) and within the distal context (culture and structural factors). This paper presents the findings of a review of research on the factors promoting and perpetuating unsafe sexual behaviour in South African youth. Papers included in the review were dated between 1990 and 2000 and addressed sexual behaviour of youth between the ages of 14 and 35 years. Both published works and unpublished reports and dissertations/theses were included. The review concluded that at least 50% of young people are sexually active by the age of 16 years; the majority of school students who had ever experienced sexual intercourse reported at the most one partner in the previous year, with a persistent minority of between 1% and 5% of females and 10-25% of males having more than four partners per year; and between 50% and 60% of sexually active youth report never using condoms. In terms of explanations for unsafe sexual behaviour among South African youth, the findings illustrate the powerful impact of the proximal and distal contexts, and in particular, the pervasive effect of poverty and social norms that perpetuate womens subordination within sexual relationships. Personal factors and the proximal and distal contexts interact to encourage HIV risk behaviour in ways that are not fully captured by social-cognitive models. The findings will be of interest to researchers and practitioners in the fields of adolescent sexual behaviour and HIV prevention in developing countries.

Accident prevention. Presentation of a model placing emphasis on human, structural and cultural factors

Abstract This paper presents a model of how three groups of accident prevention measures: modification of attitudes, behaviour, and structural conditions, are influencing two broad categories of risk factors: (a) behaviour, and (b) physical and organisational environment; and two process factors: (c) attitudes and beliefs, and (d) social norms and culture. Some of the hypothesised paths in the model seem to be weak: Attitude modification→Attitude→Behaviour→Accidents and injuries (the KAP-model), while others seem strong: Structural modification→Physical and organisational environment→Behaviour→Accidents and injuries. When various preventive measures are used in combination, and to the extent that they influence social norms and cultural factors, they are probably more effective than interventions affecting individuals (modifying factors such as attitudes and beliefs) only. Although attitude change measures seem to have little direct impact on behaviour, they may still have an important role in accident prevention. Important challenges remain to develop interventions that influence social norms and safety-related aspects of culture and to identify optimal combinations of preventive measures.

Promoting sexual and reproductive health in early adolescence in South Africa and Tanzania: Development of a theory- and evidence-based intervention programme

Aims: Action to prevent the spread of HIV among young people in Sub-Saharan Africa is needed urgently. In order to be effective, such action should be theory and evidence based and carefully adapted to local cultures and contexts. The present article describes the organization, theoretical basis, and methodological approach of a project that aims at developing and evaluating school-based interventions targeting adolescents aged 12—14 years. Methods: Researchers from European and African universities have developed interventions that were conducted in three sites: Cape Town and Polokwane (South Africa) and Dar es Salaam (Tanzania). In each site the interventions were evaluated through large-scale field experiments with intervention schools and delayed intervention schools and with baseline and two follow-up data collections. Mimimum sample sizes were estimated for each site based on local data and taking into acount that the unit of allocation was schools and not individual students (the design effect). During the formative phase as well as within the field experiments, qualitative studies were also conducted. Discussion: The interventions were developed consistent with the Intervention Mapping approach, and the theoretical framework was based on a modified version of the Theory of Planned Behaviour. The limitations of Western social cognition models were recognized, and the theoretical framework has therefore been expanded in two directions: towards integrating cultural processes and towards taking societal factors and constraints into account. Conclusion: The project will throw light on the application of social cognition models as well as the usefulness of the Intervention Mapping approach to intervention development in sub-Saharan Africa.

Subjective health complaints in adolescence: dimensional structure and variation across gender and age

AIMS The aim of this study is to investigate dimensional structures in subjective health complaints in adolescents and to examine the variation in levels and dimensionality across gender and age groups. METHODS Data from two studies were used: (1) a study based on a convenience sample, consisting of 1427 Norwegian students (11- to 15-year-olds) from schools participating in the European Network of Health Promoting Schools; (2) a nationwide survey amongst 7,059 Norwegian students (aged 11, 13, 15, and 16) from the Health Behaviour in School-aged Children (HBSC) study. Subjective health complaints were measured by revised versions of the HBSC symptoms checklist (HBSC-SCL). RESULTS In study 1 confirmatory factor analysis revealed that a model of two highly correlated factors, which can be labelled somatic and psychological, fitted the data reasonably well (CFI = 0.91). This two-factor model was applied in study 2 and latent means were tested across sub-samples defined by gender and age. The results indicate that girls show higher mean levels compared with boys on both factors. There is also an indication of an increase in these factors with age amongst girls, while amongst boys there is less, if any, difference across age groups. The correlation between the somatic and psychological factors was virtually constant across age groups and gender. CONCLUSIONS The identification of a somatic and a psychological factor indicates the existence of two different dimensions that may have different aetiologies. The gender difference in latent means across age groups may suggest a different developmental pattern amongst girls and boys.

Decline in respiratory symptoms in service workers five months after a public smoking ban

Objective: To evaluate the effect of a total ban on smoking indoors in restaurants and other hospitality business premises in Norway, on respiratory symptoms among workers in the industry. Methods: Phone interviews with 1525 employees in the hospitality business were conducted immediately before the enacting of the law. In a follow-up study five months later, 906 of the workers from the baseline sample participated. Questions were asked on demographic variables, passive smoking exposure, personal smoking, attitudes towards the law, and five respiratory symptoms. Change in symptom prevalence was analysed with McNemar’s test and with analysis of variance (ANOVA) for repeated measures. Results: The prevalence of all five symptoms declined after the ban; for morning cough from 20.6% to 16.2% (p < 0.01); for daytime cough from 23.2% to 20.9%; for phlegm cough from 15.3% to 11.8% (p < 0.05); for dyspnoea from 19.2% to 13.0% (p < 0.01); and for wheezing from 9.0% to 7.8%. ANOVA showed that the largest decline in symptom prevalence was seen among workers who themselves gave up smoking, and subjects with a positive attitude towards the law before it took effect. Conclusion: A significant decrease in respiratory symptoms among service industry workers was found five months after the enacting of a public smoking ban.

A review of studies of sexual behaviour of school students in sub-Saharan Africa

AIMS This is a review of articles on sexual behaviour of school students in sub-Saharan Africa published between 1987 and 1999. The objective was to describe what is known in this regard and identify gaps in knowledge. METHODS Literature search using electronic databases and a thumb search of relevant journals identified 47 articles reporting sexual behaviours of school-based young persons aged between 14 and 24 years. RESULTS The findings indicate a relatively low number of articles when one considers the scope of the problems related to adolescent sexual behaviour in the region; high prevalence rates of sexual intercourse; infrequent use of condoms and other contraceptives; and significant proportions of adolescents who have two or more lifetime sexual partners. More data are needed on the extent to which adolescents engage in non-penetrative sexual behaviour and penetrative sex other than heterosexual vaginal intercourse; characteristics of the sexual partners of adolescents; and proximal psychosocial antecedents of sexual behaviour and consistent risk-reduction behaviours. CONCLUSIONS Cultural influences on sexual behaviour, the sensitivity of such research in adolescent populations, and the opportunity afforded by school systems for intervention suggest a need for additional exploratory and methodological studies. Placing such information firmly within sociocultural contexts in which young people are raised will better inform effective interventions that both delay the onset of sexual intercourse and encourage use of risk reduction strategies.

Effectiveness of postal smoking cessation advice: a randomized controlled trial in young men with reduced FEV1 and asbestos exposure

There have been few community-based randomized, controlled intervention trials for cessation in high-risk smokers. In such a trial we evaluated the effects of postal smoking cessation advice in smokers with asbestos exposure and/or reduced forced expiratory volume in one second (FEV1). All men aged 30-45 yrs (n=22,392) living in 34 municipalities in western Norway were invited to a cross-sectional community survey. Information on smoking habits and occupational asbestos exposure were obtained from self-administered questionnaires and measurements of FEV1 were performed with dry-wedge bellow spirometers. Among 16,393 participants we identified a group of 2,610 smokers with previous occupational asbestos exposure and/or adjusted FEV1 in the lowest quartile. A random half (n=1,300) received a mailed personal letter from a respiratory physician with a person-specific health advice to quit smoking and a pamphlet on smoking cessation. The remaining smokers (n=1,310) acted as controls and did not receive any information. Twelve months after the intervention, information on smoking habits was re-examined using a postal questionnaire. Among the respondents (n=2,282), smoking cessation was reported altogether by 13.7% in the intervention group versus 9.9% in the control group (p<0.01). The 1 yr sustained quit rate (no smoking at all during the last year) was 5.6 versus 35% (p<0.05), respectively. Measurements of carbon monoxide in expired air (with < or = 10 parts per million) confirmed self-reported nonsmoking in samples of the two groups. In a community this simple postal smoking cessation advice from a respiratory physician based on person-specific risk factors improved the 1 yr sustained success rate by 60% in identified high-risk smokers.

Correlates of intention to use condoms among Sub-Saharan African youth: The applicability of the theory of planned behaviour

Aims: To test the applicability of an extended version of the theory of planned behaviour for the study of condom use intentions among large samples of young people in South Africa and Tanzania. Methods: Baseline data of a randomized controlled trial of school-based HIV/AIDS prevention programmes were used. The setting comprised secondary schools in the regions of Cape Town, Polokwane and Dar es Salaam. Participants were 15,782 secondary school students. The main measures were scales for intentions, knowledge, risk perceptions, attitudes, perceived social norms and perceived self-efficacy regarding condom use. Results: Seven variables accounted for 77% of the variance in intentions to use condoms: attitudes (β = 0.17), injunctive norms (β = 0.27), self-efficacy (β = 0.41), gender (lower condom use intentions among females), being a student at the Dar es Salaam site (lower scores than students in Cape Town and Polokwane), socioeconomic status (higher intentions with higher status), and access to condoms (higher intentions with higher access). Conclusions: Our results are comparable to those of studies conducted in Europe and the USA. Social cognition models such as the theory of planned behaviour are applicable in understanding the correlates of condom use intentions in African contexts.
