Independent and combined association of parity and short pregnancy with obesity and weight change among Indian women

Abstract

Objective: To investigate association of parity and short pregnancy with obesity and weight change in Aggarwal Baniya women. Method: A cross-sectional analysis was carried out on a representative sample of 307 adult Aggarwal Baniya women aged 30 - 50 years (mean age: 38.7 ± 4.87) using multistage cluster sampling method. Weight, height, various skinfold thicknesses, waist and hip circumference were measured using standardized protocol. Various indices of obesity (BMI, WHR, WHtR, GMT) were calculated subsequently. Comparison groups were defined by the number of births (parity), short pregnancies and total pregnancies. Mean change in weight and other obesity markers were examined for each group separately. Correlation analysis was applied to see the association of childbearing on obesity. Linear regression was applied as an effective measure. Results: There was a gain in weight (3.16 kg) and increase in other obesity markers (BMI: 1.29 kg/m 2 ; WC: 2.38 cm; HC: 3.83 cm) with each increase in each parity. Significant and positive correlation (p < 0.001) was found between obesity and parity. However, negative association was found between short pregnancy and obesity parameters (BMI: –0.767 kg/m 2 ). Conclusion: Among other risk factors, high parity number may be associated with obesity in women. Therefore, interventions to prevent obesity should be targeted at women prior to initiation of childbearing. However, the impact of reproductive wastage in the form of short pregnancies on women’s obesity needs further exploration.
