The intra-country rural to urban migrant populations undergo radical socio-economic and lifestyle changes in a developing country. Therefore, it is an interesting sample in which to study nutrition pattern, anthropometry and metabolic profile. The aim of this study was to assess nutrient profile and its association with the anthropometry, percentage body fat (%BF) and blood lipids in the urban slum dwellers in northern India.
A cross sectional epidemiological descriptive study.
The study was conducted in urban slum colony of Gautam Nagar, situated in a southern area of New Delhi.
The data was recorded in 227 subjects (52 males and 175 females).
The diets averaged approximately 59-60% of energy from carbohydrates, 12-13% energy from protein, and 24-27% energy from dietary total fat. Lower intake of monounsaturated fatty acids (MUFA), a low ratio of n-6/n-3 fatty acids, a high ratio of polyunsaturated and saturated fatty acids, a high intake of erucic acid, and a low consumption of fibre and vitamin E intake were significant observations. Although their mean body mass index (BMI) was in a low range (20.5+/-4.2), %BF was high in females (26.7+/-8.6%; P=0.001), and a high prevalence of abdominal obesity was observed in both males (22%) and females (16%). Moreover, there was high prevalence of hypercholesterolemia, hypertriglyceridemia and, in particular, low levels of high-density lipoprotein cholesterol. Those consuming a high-fat diet (>30%) also consumed high MUFA, n-3 fatty acids, saturated fat and dietary cholesterol. Carbohydrate intake as percentage energy was a significant predictor of the levels of triacylglycerol in males, while in females significant predictors for triacylglycerol include intake of carbohydrate as percentage energy, age, %BF and BMI.
In this economically deprived population, now constituting approximately 30-50% of the urban population of major cities in India, such adverse dietary, anthropometric and metabolic factors are predictors of early and accelerated atherosclerosis.

在发展中国家，国内从农村到城市的移民人口经历了剧烈的社会经济和生活方式变化。因此，这是一个研究营养模式、人体测量学和代谢特征的有趣样本。本研究的目的是评估印度北部城市贫民窟居民的营养状况及其与人体测量学、体脂百分比（%BF）和血脂的关系。
横断面流行病学描述性研究。
研究在位于新德里南部地区的高塔姆纳加尔城市贫民窟进行。
记录了227名受试者（52名男性和175名女性）的数据。
饮食中碳水化合物提供的能量平均约占59 - 60%，蛋白质提供的能量占12 - 13%，膳食总脂肪提供的能量占24 - 27%。显著的观察结果包括单不饱和脂肪酸（MUFA）摄入量较低、n - 6/n - 3脂肪酸比例较低、多不饱和脂肪酸与饱和脂肪酸比例较高、芥酸摄入量较高以及膳食纤维和维生素E摄入量较低。尽管他们的平均体重指数（BMI）处于较低范围（20.5±4.2），但女性的%BF较高（26.7±8.6%；P = 0.001），并且男性（22%）和女性（16%）中腹部肥胖的患病率都较高。此外，高胆固醇血症、高甘油三酯血症的患病率较高，尤其是高密度脂蛋白胆固醇水平较低。那些摄入高脂肪饮食（>30%）的人也摄入了较高的MUFA、n - 3脂肪酸、饱和脂肪和膳食胆固醇。男性中，碳水化合物能量占比是甘油三酯水平的显著预测指标，而在女性中，甘油三酯的显著预测指标包括碳水化合物能量占比、年龄、%BF和BMI。
在这个经济贫困的人群中，目前约占印度主要城市城市人口的30 - 50%，这些不良的饮食、人体测量学和代谢因素是早期和加速动脉粥样硬化的预测指标。
本研究得到了印度政府科学技术部科学与社会司的财政资助。
