3"2.2 Data Ànalvsis<br />
Three anthropometric <strong>in</strong>dicators: weight-f or-Heighr (wt/rit ) ,<br />
Height-for-Àge (gt/ege), and weight-for-Age (wt/ege) were derived from<br />
measured weight,height and estimated age. The <strong>in</strong>dicators rtlere expressed<br />
<strong>in</strong>terms <strong>of</strong> <strong>the</strong> Ì,lHO standard f or weight and height. I.ieight-f or-Àge was<br />
expressed as a percentage <strong>of</strong> <strong>the</strong> 50th percentile (median) by sex:<br />
%vttll'ge = wo/I,tst x 100, where I^7o was <strong>the</strong> observed weight and wst <strong>the</strong><br />
median for <strong>the</strong> age and sex <strong>of</strong> <strong>the</strong> chiId. Height-for-Age rvas expressed<br />
as percentage <strong>of</strong> <strong>the</strong> median <strong>in</strong> a similar manner.<br />
Perc entage<br />
weight-for-Height was calculated accord<strong>in</strong>g to <strong>the</strong> formula: % wtlut =<br />
t'¡o/wh x'100, where l.to was <strong>the</strong> observed weight and Wh <strong>the</strong> median for <strong>the</strong><br />
weight <strong>of</strong> a child <strong>of</strong> <strong>the</strong> same height and sex.<br />
The respective values <strong>of</strong> age, sex, health, and socio-economic factors<br />
(<strong>in</strong>dependent variables) were ei<strong>the</strong>r recorded as cont<strong>in</strong>uous variables or<br />
descrete variables <strong>in</strong> coded format.<br />
Four statistical procedures were used: 1. univariaLe analysis <strong>of</strong><br />
survey variables was performed to determ<strong>in</strong>e <strong>the</strong> frequency distribution<br />
<strong>of</strong> <strong>the</strong> data. 2. The stepwise regression analysis vJas carried out for<br />
dependent variables (wt/Ht, Ht/Age, and l.it/Àge) aga<strong>in</strong>st <strong>in</strong>dependent<br />
variables (study variables) to determ<strong>in</strong>e significant regressors <strong>of</strong> <strong>the</strong>
