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.

The effect of different apo(a) isoforms on plasminogen activation in black South African subjects.

OBJECTIVE: The present study evaluates the effect of different apolipoprotein(a) [apo(a)] isofroms on plasminogen activation. DESIGN: A cross-sectional study. SETTING: A rural village (Dikgale district) in the Northen Province of South Africa. SUBJECT: A total of 90 apparently healthy subjects (64 females and 36 males) aged 43 to 67 years participated in the study. RESULTS: The mean lipoprotein(a) [ Lp(a)] level in the subjects was 38.14 +/- 22.34 mg/dl. No association was found between Lp(a) isoforms. When the ratio of Lp(a):plasminogen was less then 1.3, a competitive inhibition was observed, but when the ratio exceeded 1.3, an uncompetitive inhibition was observed with all isoforms. CONCLUSION: The results of the present study suggest that the inhibition of plasminogen activation by Lp(a) is not dependent of apo(a) size.
