To study percentile distance growth pattern of Body Mass Index (BMI) of Punjabi male and female infants.
Longitudinal.
Growth Clinic.
154 Punjabi infants (Male 86; Female 68), aged birth-12 months.
FOLLOW-UP: Nude body weight and crownheel length of all babies at birth and whereafter, were measured at monthly age intervals with time tolerance to +/-3 days by the same investigator upto 12 months of life.
Mean (+/- SD) values for BMI measured 12.2 +/- 1.40 kg/m2 and 16.5 +/- 1.40 kg/m2 at birth and 12 months, respectively in male infants. The corresponding figures for female infants were 12.5 +/- 1.60 kg/ m2 and 16.5 +/- 1.50 kg/m2. A rapid increase in BMI values amongst infants of both sexes between birth to about six months followed by flattening of curves upto 12 months of age indicates an age dependent nature of BMI during first half of infancy in comparison to latter half during which these demonstrated stable trend. These findings are in contrast to those of the western infants who showed a regular increase in BMI throughout the first year of life. Sex differences were not significant at majority of the age levels.
Percentile grids presented for BMI represent a normal, healthy and well-nourished infant population which can be used to assess the adiposity status of infants of the two sexes during the first year of life.
研究旁遮普邦男、女婴儿体重指数（BMI）的百分位数距离增长模式。
纵向研究。
生长诊所。
154名旁遮普邦婴儿（男86名；女68名），年龄从出生至12个月。
所有婴儿在出生时测量裸体重和顶臀长，之后由同一名研究人员在每月龄时进行测量，时间误差控制在±3天内，直至12个月龄。
男婴出生时和12个月时BMI的均值（±标准差）分别为12.2±1.40kg/m²和16.5±1.40kg/m²。女婴相应的数据分别为12.5±1.60kg/m²和16.5±1.50kg/m²。两性婴儿在出生至约6个月期间BMI值迅速增加，随后曲线趋于平缓直至12个月龄，这表明与后半期（后半期BMI呈稳定趋势）相比，婴儿期前半段BMI具有年龄依赖性。这些发现与西方婴儿不同，西方婴儿在生命的第一年BMI呈规律性增加。在大多数年龄水平上，性别差异不显著。
所呈现的BMI百分位数网格代表了正常、健康且营养良好的婴儿群体，可用于评估两性婴儿在出生后第一年的肥胖状况。
