Cardiovascular risk profile of mothers of a Portuguese birth cohort: a survey 4 years after delivery

Abstract

Objectives: The aim of this study is to estimate the prevalence of smoking, low fruit and vegetable intake, sedentariness, overweight/obesity, abdominal obesity, hypertension, dyslipidemia and diabetes mellitus in mothers of a Portuguese birth cohort, 4 years after delivery. Methods: A birth cohort was assembled at public maternities of Porto (2005–2006). Children and mothers were reevaluated 4 years later. In this analysis, 5435 women were included. Socioeconomic characteristics, smoking, diet and exercise were self-reported. Anthropometrics and blood pressure were measured. A subgroup of 2483 randomly selected women provided a fasting venous blood sample for lipid and glucose measurements. Results: Overall, 25.3% women smoked, 71.5% consumed < 5 portions of fruit and vegetables per day, 81.3% were sedentary, 31.4% were overweight, 21.3% obese and 31.8% had abdominal obesity. The prevalence of hypertension, dyslipidemia and diabetes mellitus was 8.7%, 18.5% and 0.9%, respectively. At least one risk factor from each of the 3 groups (adverse lifestyles, adiposity and cardiometabolic comorbidities) was observed in 17.4% of women. Except for smoking, all risk factors were associated with unemployment, lower education and lower income. Conclusions: The high prevalence of unfavorable lifestyles and adiposity, and the aggregation of risk factors emphasize the adverse cardiovascular risk profile at a young age.
