Aerobic training improves quality of life in women with Polycystic Ovary Syndrome
(Lippincott, Williams & Wilkins, 2018-07) Costa, Eduardo Caldas; Sá, Joceline Cássia Ferezini de; Stepto, Nigel Keith; Costa, Ingrid Bezerra Barbosa; Farias Junior, Luiz Fernando; Moreira, Simone da Nóbrega Tomaz; Soares, Elvira Maria Mafaldo; Lemos, Telma Maria Araujo Moura; Browne, Rodrigo Alberto Vieira; Azevedo, George Dantas de
Purpose: to investigate the effects of a supervised aerobic exercise training intervention on health-related quality of life (HRQL), cardiorespiratory fitness, cardiometabolic profile, and affective response in overweight/obese women with polycystic ovary syndrome (PCOS). Methods: twenty-seven overweight/obese inactive women with PCOS (body mass index, ≥ 25 kg·m−2; age 18 to 34 yr) were allocated into an exercise group (n = 14) and a control group (n = 13). Progressive aerobic exercise training was performed three times per week (~150 min·wk−1) over 16 wk. Cardiorespiratory fitness, HRQL, and cardiometabolic profile were evaluated before and after the intervention. Affective response (i.e., feeling of pleasure/displeasure) was evaluated during the exercise sessions. Results: the exercise group improved 21% ± 12% of cardiorespiratory fitness (P < 0.001) and HRQL in the following domains: physical functioning, general health, and mental health (P < 0.05). Moreover, the exercise group decreased body mass index, waist circumference, systolic and diastolic blood pressure, and total cholesterol level (P < 0.05). The affective response varied from “good” to “fairly good” (i.e., positive affective response) in an exercise intensity-dependent manner during the exercise training sessions. Conclusions: progressive aerobic exercise training improved HRQL, cardiorespiratory fitness, and cardiometabolic profile of overweight/obese women with PCOS. Moreover, the participants reported the exercise training sessions as pleasant over the intervention. These results reinforce the importance of supervised exercise training as a therapeutic approach for overweight/obese women with PCOS
Clustering of risk factors for cardiometabolic diseases in low-income, female adolescents
(Sociedade Brasileira de Endocrinologia e Metabologia, 2016-06) Melo, Elza Maria Fernandes Seabra de; Azevedo, George Dantas de; Silva, João Batista da; Lemos, Telma Maria Araujo Moura; Maranhão, Técia M. O.; Freitas, Ana Karla Monteiro Santana de Oliveira; Spyrides, Maria H.; Costa, Eduardo Caldas
Objective: To assess the prevalence and clustering patterns of cardiometabolic risk factors among low-income, female adolescents. Materials and methods: Cross-sectional study involving 196 students of public schools (11-19 years old). The following risk factors were considered in the analysis: excess weight, central obesity, dyslipidemia, high blood pressure, and high fasting glucose. The ratio between observed and expected prevalence and its confidence interval were used to identify clustering of risk factors that exceeded expected prevalence in the population. Results: The most prevalent risk factors were dyslipidemia (70.9%), and central obesity (39.8%), followed by excess weight (29.6%), and high blood pressure (12.8%). A total of 42.9% of adolescents had two or more risk factors, and 24% had three or more. Excess weight, central obesity, and dyslipidemia were common risk factors in the clustering patterns that showed higher-than-expected prevalence. Conclusions: Clustering of risk factors (≥ two factors) among the adolescents showed considerable prevalence, and there was a non-casual coexistence of excess weight, central obesity, and dyslipidemia (mainly low HDL-cholesterol).
Diet-Induced weight loss reduces DNA damage and cardiometabolic risk factors in overweight/obese women with polycystic ovary syndrome
(Karger Publishers, 2016-04-14) Soares, Nayara Pereira; Santos, Ana Celly Souza dos; Costa, Eduardo Caldas; Azevedo, George Dantas de; Damasceno, Débora Cristina; Fayh, Ana Paula Trussardi; Lemos, Telma Maria Araujo Moura
Aims: we aimed to investigate the impact of following a diet to induce weight loss (500 kcal deficit per day) over DNA damage and cardiometabolic risk factors in women with overweight/obesity diagnosed with polycystic ovary syndrome (PCOS). Methods: a study was conducted in Natal, RN, Brazil selecting overweight/obese (body mass index ≥25 and <39 kg/m2) women (18-35 years). The levels of DNA damage were assessed by a single cell gel electrophoresis. Repeated 24 h dietary recall questionnaires, anthropometry, biochemical profile and sex hormones were collected at baseline and after 12 weeks of intervention. Results: Women exhibiting a decrease in the markers of DNA damage: tail intensity (24.35 ± 5.86 - pre diet vs. 17.15 ± 5.04 - post-diet; p < 0.001) and tail moment (20.47 ± 7.85 - pre diet vs. 14.13 ± 6.29 - post-diet; p < 0.002). Reduction of calorie intake, weight loss, decreased sexual hormone and cardiometabolic markers such as insulin, homeostasis model assessment of insulin resistance and low-density lipoprotein cholesterol were verified In the multivariate regression analysis, quantitative insulin sensitivity check index and progesterone were responsible for the variation markers in DNA damage before the diet, losing its influence upon diet. Conclusion: DNA damage and the impact of cardiometabolic risk factors decreased after the intervention in women with PCOS, indicating the relevance of a nutritional approach in this group of patients
