Abstract

Purpose An intergenerational “mismatch,” a transition from limited to plentiful living conditions over generations, may increase cardiovascular disease risks. In a migrant population within a homogenous culture, we tested the hypothesis that an intergenerational mismatch in childhood living condition is associated with higher body mass index (BMI) and blood pressure in childhood and adolescence. Methods We used data from 6,965 native born Chinese in Hong Kong (participated in “Children of 1997” birth cohort) and migrant Chinese born elsewhere in China in 1997 (N = 9,845). We classified children into those with intergenerational mismatch (child migrants or first-generation migrants) or those without (second+-generation migrants). Generalized estimating equations were used to examine the associations of migration status (child migrants, first-generation migrants or second+-generation migrants) with age- and sex-specific BMI z-score at 8–15 years and age-, sex-, and height-specific blood pressure z-score at 11–13 years, adjusted for sex, month of birth, and age. Results Compared with second+-generation migrants, first-generation migrants had higher diastolic blood pressure z-score (.04, 95% confidence interval (CI).02,.06) and BMI z-score (.12, 95% CI.06,.18), whereas child migrants had higher diastolic blood pressure z-score (.03, 95% CI.01,.05) regardless of age at migration and higher BMI z-score if they had migrated in infancy (.17, 95% CI.11,.23). Conclusion Different relations for blood pressure and BMI suggest that intergenerational mismatch and proximal exposures may have different impacts on adiposity and blood pressure. © 2017 The Society for Adolescent Health and Medicine
