Prevalence of formula milk consumption among neonates of urban and rural areas of Takestan during winter, 1998

The aim of this descriptive study was to determine the prevalence of consuming formula milk in urban and rural areas of Takestan. In winter 1998, two different sampling methods were used in the urban and rural areas and finally 480 and 720 childern(aged under 2 years) were chosen, respectively, from these areas. Results show that 7.7% of childern in urban area (95% CI, 5.3% - 10.1%) and 6.5% in rural area (95% CI, 4.7% - 8.3%) are fed by formula milk. Z-test indicated that these prevalences are not significantly different. We also found out that the mentioned prevalence for girls and boys in urban area were 8.2% and 7.1% while in rural area were 5.8% and 7.2%, respectively. The logistic regression model showed that in urban area two factors "age" and "employment" of mother are significantly related to the probability of an infant being fed by formula milk. This model also indicated that infant whose mothers have a job are 4.4 times more at risk of being fed by formula milk than by breast feeding.
