Weight gain and growth in early life may influence adult pro-inflammatory and pro-thrombotic cardiovascular risk factors.
Follow-up of a birth cohort in New Delhi, India, whose weight and height were measured every 6 months until age 21 years. Body mass index (BMI) at birth, during infancy (2 years), childhood (11 years) and adulthood (26-32 years) and BMI gain between these ages were analysed in 886 men and 640 women with respect to adult fibrinogen, high-sensitivity C-reactive protein (hsCRP) and plasminogen activator inhibitor-1 (PAI-1) concentrations.
All the pro-inflammatory/pro-thrombotic risk factors were higher in participants with higher adiposity. In women, BMI at birth and age 2 years was inversely related to fibrinogen (P = 0.002 and 0.05) and, after adjusting for adult adiposity, to hsCRP (P = 0.02 and 0.009). After adjusting for adult adiposity, BMI at 2 years was inversely related to hsCRP and PAI-1 concentrations (P < 0.001 and 0.02) in men. BMI gain between 2 and 11 years and/or 11 years to adulthood was positively associated with fibrinogen and hsCRP in women and with hsCRP and PAI-1 in men.
Thinness at birth or during infancy, and accelerated BMI gain during childhood/adolescence are associated with a pro-inflammatory/pro-thrombotic state in adult life. An altered inflammatory state could be one link between small newborn/infant size and adult cardiovascular disease. Associations between pro-inflammatory markers and childhood/adolescent BMI gain are probably mediated through adult adiposity.

    ABSTRACT: The role of diet in India's rapidly progressing chronic disease epidemic is unclear; moreover, diet may vary considerably across North-South regions. The India Health Study was a multicenter study of men and women aged 35-69, who provided diet, lifestyle, and medical histories, as well as blood pressure, fasting blood, urine, and anthropometric measurements. In each region (Delhi, n=824; Mumbai, n=743; Trivandrum, n=2,247), we identified two dietary patterns with factor analysis. In multiple logistic regression models adjusted for age, gender, education, income, marital status, religion, physical activity, tobacco, alcohol, and total energy intake, we investigated associations between regional dietary patterns and abdominal adiposity, hypertension, diabetes, and dyslipidemia. Across the regions, more than 80% of the participants met the criteria for abdominal adiposity and 10 to 28% of participants were considered diabetic. In Delhi, the "fruit and dairy" dietary pattern was positively associated with abdominal adiposity [highest versus lowest tertile, multivariate-adjusted OR and 95% CI: 2.32 (1.03-5.23); Ptrend=0.008] and hypertension [2.20 (1.47-3.31); Ptrend<0.0001]. In Trivandrum, the "pulses and rice" pattern was inversely related to diabetes [0.70 (0.51-0.95); Ptrend=0.03] and the "snacks and sweets" pattern was positively associated with abdominal adiposity [2.05 (1.34-3.14); Ptrend=0.03]. In Mumbai, the "fruit and vegetable" pattern was inversely associated with hypertension [0.63 (0.40-0.99); Ptrend=0.05] and the "snack and meat" pattern appeared to be positively associated with abdominal adiposity. Cardio-metabolic risk factors were highly prevalent in this population. Across all regions, we found little evidence of a Westernized diet; however, dietary patterns characterized by animal products, fried snacks, or sweets appeared to be positively associated with abdominal adiposity. Conversely, more traditional diets in the Southern regions were inversely related to diabetes and hypertension. Continued investigation of diet, as well as other environmental and biological factors, will be needed to better understand the risk profile in this population and potential means of prevention.

    ABSTRACT: The relationship between reproductive factors and the risk of mortality from cardiovascular disease in postmenopausal women is unclear. In this study, we aimed to investigate this relationship in Korean postmenopausal women. Subcohort analysis was carried out using the data of 3,257 postmenopausal women (age, ≥55 y at study entry) from the Kangwha Cohort Study who were followed up from 1985 until 2005. Cox proportional hazards models were used to evaluate the associations between reproductive factors and cardiovascular disease mortality. The risk of cardiovascular mortality in women who were 20 to 22 years old at first childbirth was 26% lower (95% CI, 0.60-0.92) than that in women younger than 20 years at first childbirth, after adjustment for age at entry, body mass index, hypertension, drinking, smoking, education, and occupation. Early first childbirth was associated with increased cardiovascular disease mortality (P trend = 0.036). The risk of coronary heart disease mortality was 51% lower in women who were 17 to 18 years old at menarche (95% CI, 0.25-0.95) than that in women who were younger than 17 years at menarche. An inverse relationship between age at first childbirth and the risk of cardiovascular disease mortality exists. In addition, early menarche may be a reproductive risk factor for coronary heart disease mortality.
