Table 3.2 – Self-declared heritage <strong>of</strong> participants Heritage Number % <strong>Status</strong> Indian 128 61.8 Non <strong>Status</strong> Indian 16 7.7 Métis 41 19.8 Inuit 1 0.5 Other 20 9.7 Missing 1 0.5 Total 207 100.0 A total <strong>of</strong> 125 participants (60.9%) indicated that this was their first pregnancy (i.e. primigravid). While not all <strong>of</strong> the women who reported a previous pregnancy went to term with their past pregnancy, 69 women indicated that they had one or more children. These participants had on average 2.2 ± 1.8 children (range 1 – 8) while the median number was one child. <strong>Prenatal</strong> Health <strong>Status</strong> When asked how they would rate their health during the current pregnancy, 130 women indicated that it was good (63.4%), 70 indicated average health (34.2%) while 5 indicated that their health was poor (2.4%). Nearly one-third (32.2%) <strong>of</strong> participants indicated that they were worried about their health during this pregnancy. The majority <strong>of</strong> participants indicated that prenatal care was important (199/205, 97.1%). Table 3.3 reports data on the use and views <strong>of</strong> vitamins and supplements by participants. While the majority <strong>of</strong> women admitted to taking vitamins during their current pregnancy, only 74 (37.2%) were taking them daily even though 92.2% indicated that they felt they should be taking vitamins for good prenatal health. When asked if they had ever heard <strong>of</strong> vitamin D, 131 respondents (63.9%) indicated that they had, but only 3-2
24.2% (40/165) correctly indicated what vitamin D was important for. Fewer women were familiar with dietary sources <strong>of</strong> vitamin D as only 21.8% correctly identified foods that contained vitamin D. However, participants did have a better understanding <strong>of</strong> calcium as 72.1% correctly identified foods that contained calcium. <strong>Vitamin</strong> D is not only associated with bone health but is also needed for muscle strength and balance. Participants were asked whether they had any signs <strong>of</strong> bone pain or muscle weakness as a proxy for possible vitamin D deficiency. Only 19.4% <strong>of</strong> women indicated they suffered from bone pain at the time <strong>of</strong> the proctored interview while 24.8% reported that their arms or legs felt weak. Only 31 women (15.1%) indicated they had trouble walking, another 9.7% had problems standing, and 11.2% had reported suffering from hip problems.
