Association between parity and persistent weight gain at age 40-60 years: a longitudinal prospective cohort study.

Abstract：

OBJECTIVES:Physiological metabolic adaptations occur in the pregnant woman. These may persist postpartum and thereby contribute to an unfavourable cardiovascular disease (CVD) risk profile in parous women. The aim of the current study is to assess time-dependent changes of cardiometabolic health in parous women compared with nulliparous women. DESIGN AND SETTING:We studied data of 2459 women who participated in the Prevention of Renal and Vascular End-stage Disease study, a population-based prospective longitudinal cohort for assessment of CVD and renal disease in the general population. PARTICIPANTS:We selected women ≥40 years at the first visit, who reported no new pregnancies during the four follow-up visits. All women were categorised in parity groups, and stratified for age. OUTCOME MEASURES:We compared body mass index (BMI), high-density lipoprotein (HDL) cholesterol, blood pressure as continuous measurements and as clinical relevant CVD risk factors among parity groups over the course of 6 years using generalised estimating equation models adjusted for age. RESULTS:The BMI was significantly higher in women para 2 or more in all age categories: per child, the BMI was 0.6 kg/m2 higher. corresponding with 1.5-2.0 kg weight gain per child. HDL cholesterol was significantly lower in women para 2 or more aged 40-49 and 50-59 years: per child, the HDL cholesterol was up to 0.09 mmol/L lower. Blood pressure did not differ among parity groups in any of the age categories. CONCLUSIONS:Higher parity is associated with higher BMI, lower HDL cholesterol and a higher prevalence of cardiovascular risk factors, which is constant over time. These findings warrant for prospective research assessing determinants of cardiometabolic health at earlier age to understand the role of pregnancy in the development of CVD in women.
