Association between birth weight and prevalence of cardiovascular disease and other lifestyle-related diseases among Japanese population: JPHC-NEXT Study

抄録

Background: An association between birth weight and cardiovascular disease (CVD) in adulthood has been observed in many countries; however, only a few studies have been conducted in Asian populations.

Methods: We used data from the baseline survey (2011–2016) of the Japan Public Health Center-based Prospective Study for the Next Generation Cohort, which included 114,105 participants aged 40–74 years. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were calculated from the prevalence of present and past histories of CVD and other lifestyle-related diseases, including hypertension, diabetes, hyperlipidemia, and gout, by birth weight, using Poisson regression.

Results: The prevalence of CVD increased with lower birth weight, with the highest prevalence among those with birth weight under 1,500 grams (males 4.6%; females 1.7%) and the lowest one among those with birth weight at or over 4,000g (males 3.7%: females 0.8%). Among 88.653 participants (41,156 males and 47,497 females) with complete data on possible confounders, birth weight under 1,500g was associated with a higher prevalence of CVD (aPR 1.76 [95%CI 1.37-2.26]), hypertension (aPR 1.29 [95%CI 1.17–1.42]), and diabetes (aPR 1.53 [95%CI 1.26–1.86]) when a birth weight of 3,000–3,999 grams was used as the reference. Weaker associations were observed for birth weight of 1500–2499 grams and 2500–2999 grams, while no significant associations were observed for birth weight at or over 4000 g. The association between birth weight and the prevalence of hyperlipidemia was less profound, and no significant association was observed between birth weight and gout.

Conclusion: Lower birth weight was associated with a higher prevalence of CVD, hypertension, and diabetes in the Japanese population.
