“…Because the difference in FFM between men and women are confirmed also in the SHS population (32), the paradox effect of relative FFM deficiency on LV geometry in the context of obesity might be especially important in women to explain their increased magnitude of LV mass, a finding that is supported by previous evidence (42,43), but also requires more investigation.…”

Background Relative fat-free mass (FFM) deficiency (RFFMD) can also occur in obesity, but the impact on left ventricular mass is unknown. Methods We assessed relations among reduced FFM, obesity and left ventricular (LV) mass in a population with high prevalence of obesity. Echocardiograms were performed in 2625 participants (1694 women, 1199 non-obese) of the Strong Heart Study cohort, free of prevalent cardiovascular disease and kidney failure. FFM was estimated by bioelectric impedance and analyzed in the non-obese subpopulation in relation with sex, BMI and waist-to-hip ratio (WHR). RFFMD was estimated in the obese subpopulation as the percent of observed/predicted FFM<20th percentile of the non-obese distribution. Results RFFMD was more frequent in women than men. LV mass indices (by either height2.7 or FFM) were greater in obese with than in those without RFFMD, even after adjusting for sex and diabetes (both p<0.0001). The greater LV mass index in obesity with RFFMD was related mostly to increased LV diastolic dimension paralleling increased stroke index and cardiac index, in the presence of normal ejection fraction. RFFMD remained associated with greater LV mass index (p<0.0001) even independently of older age, greater BMI, higher systolic and lower diastolic blood pressure (all p<0.007), with negligible effect of sex, waist/hip ratio and diabetes. Conclusion In obese SHS participants, RFFMD is associated with higher levels of LV mass, an effect related to adiposity more than central fat distribution and typical of female gender. Biological mechanisms of this association have to be better explored.

“…This suggests that metabolic disorders partly mediate the association between snoring and LVH. As is known to us that hypertension ranks among the most important risk factors of LVH [ 25 ]. What’s more, it has been reported in relevant studies that snoring serves as an important independent risk factor of hypertension [ 26 , 27 ].…”

BackgroundPopulation-based investigations studying the association between snoring and left ventricular hypertrophy (LVH) are lacking. Therefore, our study aims to investigate whether snoring is significantly associated with LVH, and to make clear the effect of varying degrees of snoring intensity on LVH.MethodsA total of 10,139 participants were involved in this cross-sectional study. Snoring status and snoring intensity were evaluated by a structured questionnaire. LVH was defined as left ventricular mass index ≥51 g/m2.7 for both men and women.ResultsThe total prevalence of LVH was 10.0 %. the prevalence increased significantly in snorers according to snoring intensity, including low (10.3 %), normal (13.1 %), strong (14.7 %) and very strong (16.7 %). After adjustment for age, race, gender, educational status, physical activity, annual income, current smoking status, current drinking status, sleep duration, hypertension, body mass index, waist circumference, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, total cholesterol and fasting plasma glucose, snoring (OR, 1.371; 95 % CI, 1.147–1.637, P < 0.001) was significantly associated with LVH. In addition, among the four kinds of intensity of snoring, normal (OR, 1.436; 95 % CI, 1.126–1.832, P = 0.004), strong (OR, 1.462; 95 % CI, 1.124–1.902, P < 0.001) and very strong (OR, 1.813; 95 % CI, 1.273–2.684, P < 0.001), rather than low (OR, 1.094; 95 % CI, 0.834–1.434, P = 0.518) were significantly associated with LVH.ConclusionsSnoring is independently associated with LVH. What’s more, with the rise in snoring intensity, snoring will exert an increasing effect on LVH.

“…Em média, todas estão com alta chance de complicações metabólicas, no entanto o nível de atividade física da maioria das participantes tem sido baixo. Logo há grande necessidade de uma intervenção no estilo de vida, tanto nos hábitos alimentares quanto na prática de atividades físicas [23][24] .…”

Introdução: A insatisfação corporal é muito comum nos dias de hoje devido às exigências de um padrão ideal imposto pela sociedade. As pesquisas apontam que indivíduos obesos apresentam frequentemente insatisfação corporal, além de doenças provenientes do quadro inflamatório provocado pela obesidade, como diabetes, hipertensão e coronariopatias. Por isso é tão importante apresentar formas preventivas do ganho excessivo de peso e alternativas de tratamento através da atividade física e mudanças no estilo de vida. Objetivo: Avaliar a percepção da imagem corporal, composição corporal e nível de atividade física de mulheres com sobrepeso e obesas participantes de um projeto de emagrecimento. Materiais e métodos: Foram aplicados dois questionários, sendo a escala de silhuetas para avaliação da imagem corporal e o IPAQ (Questionário internacional de Atividade Física), para avaliação no nível de atividade física. Foram mensurados também o peso, a altura e a circunferência de cintura e quadril para análise de RCQ (Relação cintura quadril). O estudo foi realizado com 20 alunas participantes do Projeto de Extensão Universitária, intitulado: “Emagrecendo com Saúde” da Faculdade Adventista de Hortolândia. Resultados: Entre as participantes 12 apresentaram 2 a 4 pontos de distância na escala de silhuetas e oito tiveram entre 5 e 8 pontos de distância, indicando maior insatisfação na escala de silhuetas. Elas também apresentaram baixo (71%) ou moderado (29%) nível de atividade física, peso excessivo e apresentam alto risco de doenças coronarianas. Conclusão: A insatisfação corporal foi acentuada no grupo de emagrecimento, o que supostamente era esperado, pois quem procura um projeto dessa natureza, além de buscar mais saúde, muitas vezes está à procura de um corpo mais delineado.
