<em><strong>Aims:</strong></em> Modifiable lifestyle factors, as cardiorespiratory fitness (CRF) and body mass, may prevent hypertension.<br />However, it remains unclear whether blood pressure is associated with CRF, independently of body mass index (BMI). Thus, the purpose was to study the relationship between CRF, body composition and blood pressure among 40-44 year old men and women.<br /><em><strong>Methods</strong></em>: During 2007-2008, 12,900 men and women aged 30-85 years attended the sixth survey of the Tromsø study. Blood pressure (mm Hg), height (cm) and weight (kg) were measured and body mass index (BMI kg/m2) was estimated. In a sub-study, the Tromsø Activity Study, CRF [VO2max (ml/kg/min)] was objectively measured using a treadmill test among 313 healthy men and women aged 40-44 years.<br /><em><strong>Results</strong></em>: Among men and women participating in both studies, the mean BMI was 27.1 kg/m2 for men and 25.1 kg/m2 for women. Mean arterial blood pressure (MAP) was 92.4 mm Hg for men and 86.0 mm Hg for women. The proportion defined as pre-hypertensive/hypertensive (systolic/diastolic blood pressure &gt; 120/80) were 33% and 56% for women and men, respectively. The proportion of low, medium and high CRF for both sexes combined differed significantly (p &lt; 0.0001) by BMI level (&lt; 25 or ≥ 25 kg/m2). Increased fitness tended to reduce blood pressure among overweight and obese men (p trend = 0.03), whereas increased fitness tended to reduce blood pressure among normal weighted women (p trend = 0.01).<br /><em><strong>Conclusion:</strong></em> Among healthy 40-44 year old men and women in this study, BMI was positively associated and CRF was negatively associated with blood pressure. Moreover, our results suggest that BMI may be a more important factor than CRF in predicting systolic blood pressure in both sexes. However, cardiorespiratory<br />fitness and weight control may both be important targets for prevention of hypertension

Abstract Aim: The aim of this study was to determine the structure, characteristics and significance of the relationship between physical fitness, BMI and WHR on one hand and hypertension of elderly men and women on the other. Methods: The sample consisted of 1288 participants (594 men and 694 women) who live in their own households in the cities and villages of Central, Eastern and South Serbia. After the obtained classification of participants based on arterial blood pressure, 231 patients with hypertension aged 60-80 years were selected. The subsample consisted of 138 male participants, while the subsample of women was 93 participants. Predictor variables consisted of 6 variables for the evaluation of physical fitness, Body mass index (BMI) and Waist-to Hip Ratio index (WHR). Criterion variables consisted of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results: The results showed that there is a statistically significant correlation (p <0.05) between predictor variables and hypertension. Higher values of higher SBP in elderly men causes an increase in body weight due to increased body fat (BMI, WHR). In elderly women, these changes occur under the influence of increased body mass index and reduced CRF. Higher values of high DBP in elderly men cause more power and flexibility of the upper body and in elderly women greater strength in the arms and less strength in legs and CRF. Conclusions: Being overweight in both subsamples could be considered as a factor that contributes to high blood pressure.

We investigated if cardiorespiratory fitness modifies the association between obesity and the level of physical activity. In this cross-sectional study, we analyzed data from 746 adults, free of diagnosed cardiorespiratory or locomotor diseases. We analyzed sociodemographic and clinical information, cardiovascular risk factors, cardiorespiratory fitness, anthropometry, and level of physical activity (time spent in moderate-to-vigorous physical activity). Those that spent more time in moderate-to-vigorous physical activity were younger, male, with lower body mass index, without self-reported arterial blood hypertension, diabetes and dyslipidemia, non-smokers, and presented with better cardiorespiratory fitness. The linear regression coefficients showed that cardiorespiratory fitness changes according to the level of physical activity and body mass index (obesity in low cardiorespiratory fitness: β 6.0, p = 0.213, 95%CI -3.5 to 15.6; in intermediate cardiorespiratory fitness: β 6.3, p = 0.114, 95%CI -1.5 to 14.2; in high cardiorespiratory fitness: β -6.3, p = 0.304, 95%CI -18.4 to 5.8). This effect modification trend was present after adjusting the model by covariates. Cardiorespiratory fitness potentially modifies the association between body mass index and the level of physical activity. It should be routinely assessed to identify persons with overweight/ obesity with low/ intermediate cardiorespiratory fitness to prescribe individualized training.

Abstract Background: The use of contraceptives has become prevalent among women in Ethiopia. Oral contraceptive use has been suggested to trigger changes in glucose metabolism, energy expenditure, blood pressure, and body weight, among the various populations and ethnic groups. Objective: To elucidate the pattern of fasting blood sugar (FBS), blood pressure and body mass index (BMI) among combined oral contraceptive (COC) pills users, taking into account other confounding factors including socioeconomic conditions and physical activity status. Methods: An institution based cross-sectional study design was employed. A total of 110 healthy women using pills were recruited as cases. Another 110 healthy women not using any hormonal contraceptives were recruited as matched controls. A study was conducted between October 2018 and January 2019. Fasting Capillary blood sample was collected from the study participants for the estimation of the FBS level. Systolic and diastolic blood pressures were measured and means arterial blood pressure was calculated for each participant. Body weight and height were measured to compute body mass index. Data obtained was entered and analyzed using IBM SPSS version 23 software packages. Results: FBS level in users was significantly increased compared to controls (88.55 ± 7.89 vs. 86.00 ± 9.85 in users and controls respectively, P = 0.025). There was a significant difference in mean arterial blood pressure of users compared to controls (88.2 ± 8.48 vs. 86.0 ± 6.74 respectively, P=0.04). The mean weight and body mass index of users were significantly increased (P = 0.03 and P = 0.003, respectively). Changes in mean fasting blood sugar level and mean weight of users were independent (P = 0.27 and P = 0.46) to the duration of use (3-12, 13-24 and ≥ 25 months). On the other hand, changes in mean body mass index and mean arterial blood pressure of users were dependent of the duration of use (P = 0.03 and P = 0.000 respectively). Conclusions: Overall, oral contraceptive pills use appears to cause a 2.9% increase in fasting blood glucose level, a 2.5% increase in mean arterial blood pressure and a 3.9% increase in body mass index among the users.

ABSTRACT Objective To verify the multivariate relationships between eating habits, cardiorespiratory fitness, body mass index, and cardiometabolic risk factors in children. Methods This is a cross-sectional study developed in a public elementary school with 60 first- to sixth-graders. Their eating habits were assessed using the Food Frequency Survey, weight, height, and cardiorespiratory fitness, assessed according to the Projeto Esporte Brasil protocol. Moreover, the variables, high-density lipoprotein, low-density lipoprotein, glucose, insulin, C-reactive protein, adiponectin, leptin, diastolic and systolic blood pressure were evaluated. Descriptive statistics were used for data analysis and generalized estimation equations were used for the analysis of direct and indirect relations, in a multivariate analysis model with several simultaneous outcomes. Results It appears that the eating habits and cardiorespiratory fitness explain 20% of the body mass index. Cardiometabolic risk factors are explained by the relationship between eating habits, cardiorespiratory fitness, and body mass index, according to the following percentages: 29% (systolic blood pressure), 18% (diastolic blood pressure), 63% (leptin), 4% (adiponectin), 14% (C-reactive protein), 17% (insulin), 10% (high-density lipoprotein), 1% (low-density lipoprotein), 4% (glucose). It is also observed that the effects of the eating habits on cardiometabolic risk factors are indirect, that is, they are dependent on changes in the body mass index and cardiorespiratory fitness levels. Conclusions The relationship between eating habits and cardiometabolic risk factors in children is dependent on cardiorespiratory fitness and body mass index. Thus, our findings suggest a multivariate relationship between these factors.

Abstract Objectives: Depo-Provera is an injectable contraceptive method containing medroxyprogesterone acetate. It has some adverse effects like changes in menstrual pattern, loss in bone mineral density and risk of weight gain. Therefore, this study is aimed at to investigate the effects of Depo-Provera on body weight and blood pressure among Ethiopian women. Institution based cross-sectional study design was conducted from January 2017 to April 2017. Data were analyzed using SPSS version 21 software. Paired t-test, independent t-test and ANOVA were used to evaluate the presence of mean difference and relationship between changes in variables and duration of use of Depo-Provera. P-value ≤ 0.05 were considered as statistically significant. Results: The mean weight and body mass index (BMI) of Depo-Provera users were increased significantly (p=0.02 for mean body weight and p=0.019, for body mass index). There was no significant difference in mean arterial blood pressure (MAP) of Depo-Provera users compared to controls or their respective pretreatment value (p-value=0.85 for Depo-Provera users and 0.67 for non-users). The finding of this study revealed that there is an increased weight gain and BMI among Depo-Provera users compared to non-users, which really requires attention of health professionals and other stake holders.
