Resumo
A síndrome metabólica (SM) é composta por uma constelação de doenças caracterizadas por resistência insulínica, dislipidemia aterogênica e hipertensão arterial, acompanhadas de comorbidades pró-trombóticas, pró-oxidantes e pró-inflamatórias. Apresenta, como principal fator de risco a obesidade e, como etiologia, o estilo de vida não saudável, pela inadequação alimentar e/ou inatividade física. A atenção primária efetiva se faz pela mudança do estilo de vida e, na intervenção alimentar, vem ganhando força a suplementação com ácidos graxos poli-insaturados ômega-3, pelas suas propriedades redutoras dos triglicerídios, da resistência insulínica, cardioprotetoras e anti-inflamatórias. O presente trabalho teve como objetivo investigar os efeitos adicionais dos AGPI ômega-3 sobre os componentes da SM e comorbidades de adultos submetidos a programa de modificação do estilo de vida (MEV). Em ensaio clínico prospectivo, foram estudados 61 indivíduos adultos (50 ± 13,8 anos), 85% mulheres, clinicamente triados para participarem de MEV, com supervisão multiprofissional. A amostra foi dividida em 2 grupos: o controle (G1, n = 26) apenas com MEV (exercício físico de caminhada e academia supervisionados e aconselhamento alimentar) e o grupo suplementado (G2, n = 35), com intervenção com AGPI ômega-3 (3g/dia) + MEV. A duração do experimento foi de 20 semanas, com avaliações nos momentos basal (M0), após 10 semanas (M1) e 20 semanas (M2) de MEV. As avaliações incluíram atividade (tempo de esteira e VO2max) e aptidão (força muscular) físicas, hábito dietético (IAS) e ingestão alimentar (recordatório de 24 horas), antropometria (IMC e CA), pressão arterial (PA) e biomarcadores plasmáticos de dislipidemia, resitência insulínica...
The metabolic syndrome (MS) consists of a constellation of disorders characterized by insulin resistance, atherogenic dyslipidemia and hypertension, accompanied by pro-thrombotic, pro-oxidant and pro-inflammatory comorbidities. Obesity is its major risk factor, and its etiology consists of unhealthy lifestyles due to inadequate diet and/or physical inactivity. Primary care is effective if lifestyle change and dietary intervention occur, and supplementation with omega-3 polyunsaturated fatty acids (PUFA) has gained strength as a result of its cardio-protective and anti-inflammatory properties in reducing triglycerides and insulin resistance. This study aimed to investigate the additional effects of omega-3 PUFA on the components of the metabolic syndrome and comorbidities of adults participating in a lifestyle change program (LSC). In a prospective clinical trial, we studied 61 adults (50±13.8 years), 85% of whom were women clinically screened to participate in LSC with multi-professional supervision. The sample was divided into two groups: control (G1, n=26), only undergoing LSC (supervised physical exercises which included walking and a fitness program as well as nutritional counseling) and the supplemented group (G2, n=35), intervention with omega- 3 PUFA (3 g/day) + LSC. The experiment lasted 20 weeks, with assessments at the baseline time (M0), after 10 weeks (M1) and 20 weeks (M2) of LSC. The assessments included physical activity (VO2max) and fitness (muscular strength), dietary habits (HEI) and food intake (24-hour recall), anthropometric measures (BMI and WC), blood pressure (BP) and plasma biomarkers for dyslipidemia, insulin resistance (HOMA-IR), oxidative (MDA) and inflammatory (CRP) stress. For statistical comparisons, we used the SAS software, version 9.2 for Windows, with significance... (Complete abstract click electronic access below)
