Obesity has become a major problem in most developed countries. Infertility ranks high among the issues brought by excessive weight gain, particularly as it may affect male sexual function. This study investigated a population of Brazilian infertile men in an attempt to establish a relationship between obesity and infertility. A total of infertile men had their anthropometric data collected and were divided into groups according to their body mass index and waist circumference measurements. Sperm parameters including sperm count, concentration, morphology, and motility were compared. Multivariate analysis failed to show a positive correlation between excessive weight gain or increased waist circumference, and sperm alterations in a population of infertile men. The findings described in this study support the idea that there is no association between obesity and semen alterations in a population of infertile men. The World Health Organization WHO defines infertility as the inability to achieve pregnancy within 12 months of regular intercourses for couples in conception. Meanwhile, most developed nations have reported increases in the numbers of overweight and obese men and women in their reproductive years, in addition to more cases of diseases related to obesity such as hypertension, diabetes, and vascular disorders Hammoud et al.
Perceived time constraints have been highlighted in sociological studies as representing a core issue in determining quality of life. The objective of this study was to test the hypothesis that gender inequalities regarding insufficiency of time play a role in the development of overweight and obesity in adults. Insufficient time for personal care and leisure due to professional and domestic duties, as detailed in a structured questionnaire, comprised the main exposure variable.
Identification of the body fat BF percentage allows health professionals to detect healthy or risky patterns in a population. However, no studies have elaborated BF cutoff points using the bioelectrical impedance method in young Brazilian adults. Thus, the objective of the present study was to elaborate normative tables for BF in Brazilian men and women sedentary and physically active between 18 and 39 years of age. A total of 3, adults men and 2, women were evaluated using bioimpedance measurements with the InBody device. These percentiles can be used to classify the adiposity of sedentary and physically active individuals evaluated by bioimpedanciometry. SD, standard deviation; CI, confidence interval.
Metrics details. Obesity ranks as a major public health problem in many countries in the world. The obesity-socioeconomic status relationship is not well established in middle-income countries. The aim of this study was to estimate the obesity and overweight trends from to by sex, age, and educational levels among Brazilian adults. The panel prevalence trend study was conducted, considering the sample weights and study design.
