Thesis (MSc. Medical Science (Chemical Pathology)) -- University of Limpopo, 2017 / Obesity has been associated with dyslipidaemia (increased levels of triglycerides, total cholesterol and low levels of HDL-C together with small dense lipoprotein particles) in the absence of metabolic disorders such as, type 2 diabetes mellitus and inflammation. Since community based studies in South Africa reported that obesity is more common in women, and rural Africans have a more favourable lipid profile compared to their White counterparts, the current study investigated the association of obesity in women without metabolic disorders with lipid levels and changes in proportions of small and large LDL and HDL particles. Methods The present study was part of the project “Prevention, Control and Integrated Management of Chronic Disease in a rural area, South Africa”. A total of 521 women participated in the above project. After excluding people with diabetes mellitus, insulin resistance and inflammation, 308 women were left and of these 67 were obese. Sixty seven ages matched, randomly selected non-obese women served as controls. Anthropometry variables as well as systolic and diastolic blood pressures were measured and the WHO steps questionnaire was administered to collect information on medication, lifestyle and diseases. Fasting blood levels of total cholesterol, HDL C, triglyceride, adiponectin, CRP, glucose and insulin were measured. Proportions of small and large HDL and LDL particles were determined. Results There was no significant difference in TC, TG and LDL-C levels (p=0.558, 0.087 and 0.948) between obese and non-obese women or between women with increased waist circumference (WC) and those with normal WC. The HDL-C concentration was significantly lower in obese women compared to women with non- obese (p=0.001). The lipid ratios TC/HDL-C and Apo B-100/Apo A-I were significantly higher in obese women than those with non- obese (p=0.013 and p=0.006) respectively. The same phenomenon was observed in women with xv increased waist circumference (p=0.001** and p=0.025* respectively). Adiponectin levels were significantly lower in obese women compared to non-obese women (p=0.004**) and in women with increased waist circumference compared to those with normal waist circumference (p=0.016*). The proportions of small dense HDL and LDL lipoprotein particles were similar in obese and non-obese women. Both obese and abdominally obese women had significantly higher odds ratios of low levels of HDL-C and elevated Apo B-100/Apo A-I. Adiponectin was a significant predictor of elevated TC and TG in both obese and abdominally obese women while BMI was a significant predictor of low HDL-C in obese women. Waist circumference was a significant predictor of low HDL-C in abdominally obese women. Conclusion In the current study, obesity in women was significantly associated with lipid abnormalities such as low HDL-C levels, raised lipid ratios (TC/HDL-C and Apo B 100/Apo A-I) and low levels of adiponectin, after excluding metabolic disorders / VLIR

Aging, obesity and increased waist circumference (WC) increases risk for metabolic syndrome (MetS). MetS is a cluster of symptoms (elevated WC, triglycerides, blood pressure, fasting glucose, and decreased high-density lipoprotein cholesterol [HDL-C]) increasing risk for chronic disease. Low-energy dense (LED) diets, emphasizing whole food eating patterns, have not been examined in combination with moderate (mod)/high-intensity physical activity (PA) or dietary protein levels to determine their impact on changes in body weight (BW) and WC in premenopausal, abdominally obese women. PURPOSE: To determine the effect of two 16-wk diet and PA interventions, differing in protein intake, on BW, WC, MetS risk factors, dietary patterns, energy density (ED), and min of Mod-Hi PA. METHODS: Healthy, abdominally obese (WC≥80cm) women (n=38; 34±10y) were randomly assigned to either a 15 or 25% (+18 g/d whey protein) en from protein diet. Individualized LED diets plans decreased energy intake (EI) by ~300kcal/d; PA 5 d/wk (30-60 min/d) consisted of supervised, high-intensity Zumba classes 3d/wk (≥65%HRmax; ≥6METs) and self-selected mod-intensity PA (≥3METs) 2d/wk. Servings of fruits/vegetables, whole grains, and low-fat/fat-free dairy (LFD), fiber, high calorie beverages (BEV), ED, and PA were monitored before (T1), during (T2) and after (T3) the intervention using repeated measures ANOVA. Bonferroni simultaneous testing procedure was used in analysis of multiple comparisons. RESULTS: At T1, groups did not differ in dietary patterns, PA, BW, WC, or MetS risk. Groups responded similarly to the interventions so data were combined, with BW and WC decreasing (p<0.0001) by -4.8±2.7kg and -7.1±3.6cm, respectively. Comparing T1 vs. T2, there were increases (p<0.0001) in fruits/vegetables, (Δ=+1.5 ser/d), whole grains (Δ=+1.0 ser/d), LFD (Δ=+0.5 ser/d), fiber (Δ=+5.7g/1000 kcal), and decreases in BEV (Δ=-165 kcal/d) and ED (Δ=-0.55 kcal/g). During the intervention high-intensity Zumba PA was 87min/wk; total min of all mod-intensity PA increased by 75 min/d (p<0.0001); VO2max improved from 29.3±4.7 (T1) to 34.4±5.3 (T3) mL/kg/min (p<0.0001). Triglycerides significantly decreased (-24±52 mg/dl; p=0.006), no other significant changes occurred in MetS risk factors. Exploratory analysis indicated that increases in fruits/vegetables and LFD, and decreases ED were associated with BW loss, while increases in whole grains, fiber, LFD, and min/wk of high-intensity PA (Zumba) were associated with WC reductions. CONCLUSION: For abdominally obese women, an intervention focused on LED foods and high-intensity PA significantly reduced BW and WC and improved dietary patterns regardless of protein intake. Helping clients identify a few key factors that positively promote reductions in BW and WC may improve weight loss success, while reducing MetS risk factors. / Graduation date: 2012
