A comparison of weight gains during pregnancy of WIC and non-WIC clinic samples
MetadataShow full item record
The purpose of this study was to find the difference, if any, between the weight gain patterns during pregnancy of women attending public health clinics in Northern Virginia who were enrolled in the NIC program and women not enrolled in the NIC program. Women on the NIC program during pregnancy were identified from NIC files. The control group was chosen from among women who were shown to be both nutritionally at risk and eligible for NIC based on income, but who were not receiving NIC benefits during pregnancy.
The sample consisted of M8 subjects in each group who met certain other selection criteria. With the exception of income, there was no statistically significant difference when selected maternal and infant variables were compared.
There was no significant difference (p>.O5) between total weight gain of the two groups, although the NIC mothers gained slightly more during pregnancy than the non-NIC mothers. A series of t-tests, performed between the means of the weekly weight gains, showed no significant difference in the weekly weight gain of the two samples at any week of pregnancy.
Both samples had increased weekly weight gains near the end of pregnancy - the mean of the non-WIC group was higher and occurred slightly later than did that of the WIC group. These higher means near the end of pregnancy for the non-WIC group resulted in statistically significant differences in the two groups when comparing the last part of pregnancy and suggest that the non-WIC group is gaining a larger amount of weight very late in pregnancy.
