Findings from a prospective cohort study evaluating the effects of International Health Advisors' work on recently settled migrants' health.

BACKGROUND: Several interventions have been carried out to tackle health inequalities between migrant groups, especially refugees, and native-born European populations. These initiatives are often address language or cultural barriers. One of them is the International Health Advisors (IHA) in Sweden; a peer education intervention aimed at providing health information for recently settled migrants. It is known that social determinants, such as educational level and access to social capital, affect health. Social determinants may also affect how health information is received and transformed into practice. The aims of this study was to a) assess the impact of the IHA on recently settled migrants' self-reported health status, and received health information; b) determine the moderating role of educational level and social capital; and c) critically discuss the outcomes and suggest implications for health promotion practice. METHODS: The study was designed as a prospective cohort study. A postal questionnaire translated to Arabic was sent to recently settled Iraqi migrants in eight counties in Sweden, in May 2008 and May 2010. Two of the counties were exposed to the intervention, and six were used as references. RESULTS: The proportion of individuals who reported that they had received information on healthy diet and physical exercise was higher in the intervention group than in the non-intervention group (OR 2.31, 95% CI 1.02-5.22), after adjustments. Low social participation was negatively associated with deteriorated or unchanged health needs (OR 0.47, 95% CI 0.24-0.92). No other statistically significant differences in health outcomes could be observed between the groups. No signs of effect modification on this association by social capital or educational level could be found. CONCLUSIONS: Health information provided by the IHA increased self-reported level of knowledge on healthy diet and physical exercise. The interpretation of the observed negative association between low social participation and deteriorated or unchanged health needs is that participation was limited to one's own social group, and therefore had limited positive influence on health seeking behaviour. The lack of measurable improvements in health status could be explained by limitations in the study, in the theoretical assumptions underlying the intervention, and in the implementation of the intervention. Further research is needed to understand success factors in health promoting interventions among recently settled migrants better.

Does social capital protect mental health among migrants in Sweden?

Poor mental health is common among migrants. This has been explained by migration-related and socio-economic factors. Weak social capital has also been related to poor mental health. Few studies have explored factors that protect mental health of migrants in the post-migration phase. Such knowledge could be useful for health promotion purposes. Therefore, this study aimed to analyse associations between financial difficulties, housing problems and experience of discrimination and poor mental health; and to detect possible effect modification by social capital, among recently settled Iraqi migrants in Sweden. A postal questionnaire in Arabic was sent to recently settled Iraqi citizens. The response rate was 51% (n = 617). Mental health was measured by the GHQ-12 instrument and social capital was defined as social participation and trust in others. Data were analysed by means of logistic regression. Poor mental health was associated with experience of discrimination (OR 2.88, 95% CI 1.73-4.79), housing problems (OR 2.79, 95% CI 1.84-4.22), and financial difficulties (OR 2.14, 95% CI 1.44-3.19), after adjustments. Trust in others seemed to have a protective effect for mental health when exposed to these factors. Social participation had a protective effect when exposed to experience of discrimination. Social determinants and social capital in the host country play important roles in the mental health of migrants. Social capital modifies the effect of risk factors and might be a fruitful way to promote resilience to factors harmful to mental health among migrants, but must be combined with policy efforts to reduce social inequities.

Health information for migrants: the role of educational level in prevention of overweight.

AIMS: Modifiable risk factors for cardiovascular disease include overweight, which is prevented by healthy diet and physical activity. Recently settled migrants may have varying levels of exposure to health information. Therefore, the objectives of this study were to explore the associations between self-reported information on healthy diet and on physical activity and overweight and the possible modification of this association by educational level among recently settled Iraqi migrants in Sweden. METHODS: Cross-sectional data were collected through a postal questionnaire in Arabic and analysed by means of logistic regression. Dummy variables were created in order to assess the possible modification by educational level on the association between health information and overweight. RESULTS: After adjustments for potential confounders, associations were found between overweight and not having received information on healthy diet (OR 1.56, 95% CI 1.07-2.27) and physical exercise (OR 1.58, 95% CI 1.07-2.32). Educational level modified these associations, so that the impact on overweight by information was much more evident among those with a high level of education. CONCLUSIONS: The findings showed that overweight was associated to perceived lack of health information among recently settled Iraqi migrants. It may be easier for migrants with high education to seek, receive, and understand health-related information. Migrants with low education may be more traditional in, for example, their diet and therefore less likely to be overweight. Culturally adapted information may therefore not be relevant for them. The broader context of the social determinants of health needs to be considered when planning interventions for migrants.
