Abstract
A cross-sectional study of 191 adult (>18 years) Bengalee male slum dwellers of Kolkata, India, was undertaken to study the relationships of family income with body mass index (BMI) and chronic energy deficiency (CED). Results revealed that the mean height, weight, and BMI of the subjects were 162.2 cm, 54.0 kg, and 20.5 kg/m2, respectively. The overall frequency of CED (BMI < 18.5 kg/m2) was 33.5%. Based on the World Health Organization classification, the prevalence of CED among this population was high (20–39%) and thus the situation is serious. Overall, monthly family income (MFI) was significantly positively correlated (r = 0.18, p < 0.05) with BMI. Linear regression analyses showed that MFI had significant impact (p < 0.05) on BMI. The percent variation in BMI explained by MFI was 2.6%. Subjects belonging to the lowest family income group (FIG) had the lowest mean BMI (19.5 kg/m2) and the highest rate of CED (46.6%) while those in the highest FIG had the largest mean BMI (21.4 kg/m2) and lowest rate of CED (23.1%). There was a significant FIG difference (F = 2.965, p < 0.05) in mean BMI. Moreover, there existed FIG differences (χ 2 = 7.54, p < 0.06) in CED rates. In conclusion, this study provided strong evidence that FIG was significantly associated with BMI and the presence of CED. The rate of CED was high, indicating a serious situation. These findings may have severe public health implications. It is recommended that immediate nutritional intervention programs be initiated among this population along with serious efforts to increase their family income.
