Social support and arterial pressure in a central Mexican community

&NA; Research on the relationship of social support and arterial blood pressure was conducted in a town in central Mexico. A culturally appropriate measure of social support was developed assessing perceived support from relatives, friends, neighbors, and compadres (ritual kin). The effects of perceived support from these four sources were compared to the effects of the amount of reported social contacts. For males, more support from all four sources was related to lower arterial pressure, whereas amount of social contact was related to higher diastolic blood pressure; support from compadres had the largest inverse correlation with blood pressure. For females the pattern of correlations was dependent on age: support from relatives and friends was related to higher blood pressure for younger females, whereas support from relatives was related to lower blood pressure for older females. This pattern of relationships is consistent with the place of women in the social structure of this Mexican community, and these results point to the need to conceptualize and measure social support in culturally appropriate ways.

A comparison of binge-purgers, obese binge eaters, and obese nonbinge eaters on the MMPI

This study compared the (MMPI) score distributions obtained by binge-purgers (n=34), obese binge eaters (n=34), and obese nonbingers (n=34) of similar age. Significant differences emerged among the three groups on all MMPI scales except Masculinity-feminity (Mf) and Mania (Ma), and there was a consistent trend on the clinical scales for binge-purgers to obtain the highest scores and obese nonbingers the lowest. Obese binge eaters were statistically different from obese nonbingers on 10 of 13 scales and from binge-purgers on 4 of 13 scales. The results suggest that these groups represent three distinct populations, with obese nonbingers exhibiting the least psychological disturbance and binge-purgers exhibiting the most

Social and dietary predictors of serum lipids: a Brazilian example.

The importance of an unfavorable profile of serum lipids in the atherosclerotic process has been unequivocally established, but the determinants of serum lipids remain a source of controversy. This controversy includes both the importance of diet as a precursor of an unfavorable lipid profile, and the potential importance of social and psychological factors in determining lipid values. These questions were addressed in a study of serum lipids in urban Brazil. It was found that both dietary and social-psychological factors were associated with total serum cholesterol, high density lipoprotein cholesterol, and serum triglycerides. This exploratory study highlights the importance of the careful measurement of dietary intake, and the inclusion of theoretically relevant social and psychological variables, in any study of serum lipids.

Social factors mediating social class differences in blood pressure in a Jamaican community

Research on the factors mediating social class differences in blood pressure was carried out in a Jamaican community. It was found in a previous report that higher social class is related to lower blood pressure for females, while for males higher social class is related to higher blood pressure. These differences are examined in greater detail here, especially in terms of the historical context of the specific community studied, which is on the fringe of the Kingston urban area, and in terms of the continuing importance of a social class system established under colonial rule. In the current study it is shown that social class differences in blood pressure for males are mediated by perceptions of social support. Social class differences in blood pressure for females are mediated by perceptions of economic stress. It is suggested that specific patterns of the growth of the city, and the historically-based social class system, have resulted in the juxtaposition of lower and middle class Jamaicans within this community, who in turn are influenced by different factors affecting blood pressure.

Blood pressure and social class in a Jamaican community.

A study of social factors and blood pressure was conducted in a Jamaican community among a sample of 199 persons ages 30 to 50. After controlling for obesity, age, and respondent tension (and other covariates), interaction effects of social class x sex for systolic and diastolic blood pressure were found. Blood pressure increased with increasing social class for males and decreased with increasing social class for females.
