Several studies have shown that there is a significant relationship between relative weight and hypertension. The anatomical distribution of weight has also been shown to be a factor in determining which people are more susceptible to hypertension and thus at risk of developing cardiovascular diseases. This study investigated the relationship between two anthropometric measurements for obesity-body mass index (BMI) and waist-hip ratio (W HR), and the blood pressure of Nigerians aged 15-85 years. The study employed a cross-sectional survey of individuals living in Ibadan North Local Government Area of Oyo State. Four hundred and four male and female individuals were recruited using a non-probability sampling technique. Measurements taken include subjects' systolic and diastolic blood pressure, waist and hip girths, height, and weight. Information was obtained about lifestyle and occupation as well as familial history of hypertension, diabetes, cardiac and renal diseases. Data was analysed using descriptive and inferential statistics, with alpha set at 0.05. Results show that WHR and BMI had a linear relationship with the blood pressure of the participants.
BackgroundThe development of gout is associated with obesity and metabolic syndrome (MS). Obesity is defined by body mass index (BMI). However, BMI has being challenged for the limitation of not distinguishing different comprising tissues of the body. Body composition (BC) has been frequently recommended to assess metabolic status and will eventually replace BMI as a more reliable measure.ObjectivesTo investigate the characteristics of BC in gout patients and their significance with disease characteristics.MethodsBC was assessed in 180 consecutive gout patients and1,860 control subjects (white-collar employees in Zhangjiang InnoPark of Shanghai) by bioelectric impedance analysis. Overfat was defined by body fat percentage (BF%) as ≥25% for men and ≥35% for women. Demographic and clinical data as well as comorbid diseases were collected simultaneously. For the significant differences in the proportion of gender and age between two groups, the age- and gender-matched control subjects were randomly selected with the ratio of 1:1 for further statistics.Results(1)Among 180 gout patients recruited, the mean age was 42.5±15.5 years, mean serum uric acid (sUA) was 9.0±2.4 mg/dl and 17.2% of patients presented tophi. The mean BMI was 25.4±3.5 kg/m2 with 44.4% overweight and 25.6% obesity. The mean BF was 26.2%±6.6% with 50.5% overfat. (2)Compared with control subjects, gout patients were characterised by higher BMI (25.4±3.5 kg/m2 vs. 24.3±3.3 kg/m2), fat mass (19.3±6.9 kg vs. 16.5±6.2 kg), trunk fat mass (10.2±5.4 kg vs. 8.4±3.4 kg), BF (26.2%±6.6% vs. 22.4±6.2%), proportion of overfat (50.5% vs. 27.2%), but lower lean mass (53.0±7.7 kg vs. 55.6±7.7 kg, all p<0.05). (3)Compared with normal fat patients (n=89), gout patients with overfat (n=91) presented higher duration of gout, the count of affected joints, flare times in the past year, family history and presence of tophi (all p<0.05, table 1). Overfat gout patients also exhibited higher BMI, more obesity, hyper-low density lipoproteinemia, MS and fatty liver (all p<0.05). (4)There were 9 (17.3%) overfat gout patients in 53 normal weight patients who presented more hypercholesterolemia (55.6% vs. 13.3%), hyper-low density lipoproteinemia (55.6% vs. 17.8%) and fatty liver (77.8% vs. 35.6%) and less skeletal muscle mass index (SMMI, 8.3±0.5 kg/m2 vs. 9.7±0.7 kg/m2) than those patients with normal fat and weight (all p<0.05). Meanwhile, there were 44 (34.9%) gout patients with normal fat among 126 overweight and obesity patients who had less MS (40.9% vs. 63.4%) and more SMMI (11.1±0.9 kg/m2 vs. 10.6±1.1 kg/m2) than overfat patients (both p<0.05). (5)Overfat was a risk factor for MS [OR 3.4 (1.8, 6.4), p<0.001] after adjusted by age and gender.Abstract AB1032 – Table 1Comparison of disease characteristics between gout patients in BF subgroupsBMI: body mass index; SMMI: skeletal muscle mass indexConclusionsOur results indicated higher body fat in gout patients which is an independent risk factor for MS.AcknowledgementsThe present study was supported by Guangdong Natural Scie...
SUMMARYIn order to achieve optimum health status, Type 2 Diabetes (T2D) patients are usually encouraged to undergo regular and consistent therapeutic exercises. This study investigated whether the gains of exercises on adiposity variables of T2D patients are maintained within a few weeks of withdrawal from exercise and whether it was significantly related to the age of the patient and the duration of diagnosis of T2D.Forty-threeT2D patients aged between 30 and 64 years were recruited for this study. They were placed on a combination of endurance and strengthening exercises for 12 weeks. The participants were thereafter observed for another 12 weeks without exercises. The adiposity variables measured in both phases of the study include: body mass index (BMI), waist circumference (WC), waist-hip-ratio (WHR) and percent-body-fat (PBF).Significant improvements (P<0.05) for all the variables were achieved after 12 weeks of therapeutic exercises. The variables, however, showed significant relapses (P<0.05) within six weeks of withdrawal of exercise and these were significantly related (P<0.05) to both the age of the patient and the duration of diagnosis.The endurance and strengthening exercises improved the adiposity variables of theT2D patients, but the gains began to decline within six weeks of withdrawal from the exercises. The increase in adiposity was more as the age and duration of diagnosis of the patients increased.
