Although the relationship between socioeconomic status (SES) and health is well-established in Western industrialized countries, few studies have examined this association in developing countries, particularly among older cohorts. We use the Mexican Health and Aging Study (MHAS), a nationally representative survey of Mexicans age 50 and older, to investigate the linkages between three indicators of SES (education, income, and wealth) and a set of health outcomes and behaviours in more and less urban areas of Mexico. We consider three measures of current health (self-rated health and two measures of physical functioning) and three behavioural indicators (obesity, smoking, and alcohol consumption). In urban areas, we find patterns similar to those in industrialized countries: higher SES individuals are more likely to report better health than their lower SES counterparts, regardless of the SES measure considered. In contrast, we find few significant SES–health associations in less urban areas. The results for health behaviours are generally similar between the two areas of residence. One exception is the education–obesity relationship. Our results suggest that education is a protective factor for obesity in urban areas and a risk factor in less urban areas. Contrary to patterns in the industrialized world, income is associated with higher rates of obesity, smoking, and excessive alcohol consumption. We also evaluate age and sex differences in the SES–health relationship among older Mexicans. The results suggest that further economic development in Mexico may lead to a widening of socioeconomic inequalities in health. The study also provides insight into why socioeconomic gradients in health are weak among Mexican-Americans and underscores the importance of understanding health inequalities in Latin America for research on Hispanic health patterns in the US.
Perceived social position and health in older adults in Taiwan

The authors examined whether perceived social position predicted mental and physical health outcomes (depressive symptoms, cognitive impairment, mobility restrictions, and self-assessed health) in a prospective study based on a nationally representative sample of older persons in Taiwan. Cross-sectional and longitudinal models were used to demonstrate the relationship between perceived social position and health, as reported by participants in the Social Environment and Biomarkers of Aging Study in Taiwan (SEBAS). Lower perceived social position predicted declining health beyond what was accounted for by objective indicators of socioeconomic position. As predicted, the effect was substantially reduced for all health outcomes in the presence of controls for baseline health. After including these controls, perceived social position was significantly related only to depressive symptoms. The findings suggest that the strength of the association between perceived social position and health may have been overstated in cross-sectional studies.
Why do Hispanics in the USA report poor health?

Despite the health and survival advantages of Hispanics relative to non-Hispanic whites in the USA, Hispanics report themselves to be in worse health than whites. Prior research indicates that these ethnic differences in self-rated health (SRH), measured by a simple question asking individuals to assess their overall health status, persist in the presence of an extensive set of explanatory variables. The study uses data from the first wave of the Los Angeles Family and Neighborhood Survey (L.A.FANS-1) to test three hypotheses regarding Hispanic–white differences in SRH. The authors evaluate whether poorer health reports among Hispanics result from: (1) acculturation and language-related differences in reports; (2) measures of socioeconomic status (SES) that are often omitted in other studies; and (3) somatization of emotional distress by Hispanics. These results provide new insights into the validity of these explanations and suggest avenues for future research. First, they underscore the importance of language of interview over other measures of acculturation, suggesting that translation issues between the Spanish and English versions of the SRH question may give rise to some of the differences. Second, adjustment for SES - especially years of schooling - narrows, but does not eliminate, the gap between whites’ and Hispanics’ SRH. Finally, although respondents who are depressed are more likely to report poor SRH, this study provides little evidence to support the somatization hypothesis. The second wave of L.A.FANS incorporates new questions that are likely to permit more in-depth assessments of these hypotheses in future analyses.
