Effect of high parity on occurrence of anemia in pregnancy: a cohort study
<p>Abstract</p> <p>Background</p> <p>Studies that explore the controversial association between parity and anaemia-in-pregnancy (AIP) were often hampered by not distinguishing incident cases caused by pregnancy from prevalent cases complicated by pregnancy. The authors' aim in conducting this study was to overcome this methodological concern.</p> <p>Methods</p> <p>A retrospective cohort study was conducted in Oman on 1939 pregnancies among 479 parous female participants with available pregnancy records in a community trial. We collected information from participants, the community trial, and health records of each pregnancy. Throughout the follow-up period, we enumerated 684 AIP cases of which 289 (42.2%) were incident cases. High parity (HP, ≥ 5 pregnancies) accounted for 48.7% of total pregnancies. Two sets of regression analyses were conducted: the first restricted to incident cases only, and the second inclusive of all cases. The relation with parity as a dichotomy and as multiple categories was examined for each set; multi-level logistic regression (MLLR) was employed to produce adjusted models.</p> <p>Results</p> <p>In the fully adjusted MLLR models that were restricted to incident cases, women with HP pregnancies had a higher risk of AIP compared to those who had had fewer pregnancies (Risk Ratio, RR = 2.92; 95% CI 2.02, 4.59); the AIP risk increased in a dose-response fashion over multiple categories of parity. In the fully adjusted MLLR models that included all cases, the association disappeared (RR = 1.11; 95% CI 0.91, 1.18) and the dose-response pattern flattened.</p> <p>Conclusions</p> <p>This study shows the importance of specifying which cases of AIP are incident and provides supportive evidence for a causal relation between parity and occurrence of incidental AIP.</p
The risk of metabolic syndrome as a result of lifestyle among Ellisras rural young adults
The study aimed to investigate the association between metabolic syndrome (MetS) and lifestyle risk
factors among Ellisras
adults. A cross-sectional study was conducted on 624 adults (306 males and 318 females). MetS was
defined according to the criteria of the International Diabetes Federation. The prevalence of MetS
was 23.1% (8.6% males and 36.8 % females). Females appeared to have higher mean values for waist
circumference (WC), fasting blood glucose (FBG), total cholesterol (TCHOL) and low-density
lipoprotein cholesterol (LDL-C), while males had high mean values for high-density lipoprotein
cholesterol (HDL-C), triglycerides (TG), systolic blood pressure (SBP) and diastolic blood pressure
(DBP). No significant age and gender differences were observed for dietary intake. Significantly more
females (51.9%) presented with increased WC than males (4.6%). Participants who had a high dietary
energy intake were significantly less likely to present with larger WC (OR: 0.250 95% CI [0.161;
0.389]), low HDL-C (OR: 0.306 95% CI [0.220; 0.425]) and high LDL-C (OR: 0.583 95%
CI [0.418; 0.812]) but more likely to present with elevated FBG (OR: 1.01 95% CI [0.735; 1.386]),
high TCHOL (OR: 1.039
95% CI [0.575; 1.337]), high TG (OR: 1.186 95% CI [0.695; 2.023]) and hypertension (OR: 5.205 95%
CI [3.156; 8.585]).
After adjusting for age, gender, smoking, and alcohol status, high energy intake was more than two
times likely to predict MetS in adults with a large WC (OR: 2.766 95% CI [0.863; 3.477] and
elevated FBG (OR: 2.227 95% CI [1.051; 3.328]). Therefore, identifying groups that are at an
increased risk and those that are in their early stages of MetS will help improve
and prevent the increase of the MetS in the future
