Beneficios de una intervención educativa en la dieta y en el perfil antropométrico de mujeres con un factor de riesgo cardiovascular

BACKGROUND AND OBJECTIVE To assess whether an educational intervention in perimenopausal women with hypertension, diabetes mellitus and/or dyslipidaemia would improve adherence to a Mediterranean diet pattern and achieve changes in anthropometric parameters. PATIENTS Randomized clinical trial of parallel groups: 320 women (45-60 years) in 2 urban primary care services. VARIABLES STUDIED hip and waist circumference, body mass index (BMI), total, visceral and trunk fat (bioimpedance measures) and adherence to Mediterranean diet (MEDAS-14 questionnaire). Intervention group: 3 interactive workshops on prevention of cardiovascular disease, and control group: information by post. RESULTS Two hundred and thirty women completed the study (113 control group and 117 intervention group). The differences between groups were significant in all parameters one year later. In the intragroup comparison, the intervention group maintained their BMI and improved adherence to the Mediterranean diet. The control group increased their BMI, abdominal and hip circumference and fat parameters (total, visceral and trunk fat). CONCLUSIONS A simple educational intervention in perimenopausal women with cardiovascular risk can improve their healthy habits.

Síndrome metabólico y grasa visceral en mujeres con un factor de riesgo cardiovascular

INTRODUCTION Cardiovascular diseases are the leading cause of death in women after menopause, since after this stage there are profound metabolic and hormonal changes which favor the development of metabolic syndrome. An increase in the percentage of visceral fat may be related to the onset of this syndrome. OBJECTIVE To establish the relationship between visceral fat and parameters of the metabolic syndrome and to determine the optimal cut-off point for the variables related to obesity in women with a cardiovascular risk factor. METHOD Cross-sectional descriptive study carried out in two urban health centers in Spain. We evaluated 320 women aged 45 to 60 years with hypertension, diabetes mellitus and/or dyslipidemia. Age, estrogenic activity, visceral fat and body fat measured through a bioimpedance device, body mass index, abdominal perimeter, systolic and diastolic blood pressure, triglycerides, high density lipoprotein, glucose and the presence or absence of syndrome metabolic were considered. RESULTS There is a significant correlation between visceral fat and all metabolic syndrome defining parameters (p < 0.05). The optimum cut-offs for obesity-related variables were visceral fat (8 kg), abdominal perimeter (93.5 cm), body mass index (26.9 kg/m2 ) and total body fat (24.3 kg). CONCLUSIONS Menopausal women showed more visceral fat. An association between visceral fat and the parameters that define the metabolic syndrome is observed. It would be advisable to perform a more complex research to study the utility of visceral fat as a possible screening parameter in the metabolic syndrome.

Intervención educativa sobre parámetros cardiovasculares en mujeres perimenopáusicas con un factor de riesgo cardiovascular. Ensayo clínico aleatorizado

BACKGROUND AND OBJECTIVE Randomised clinical trial performed in two urban health centres in Spain. To evaluate if educational intervention in women of perimenopausal age with hypertension, diabetes mellitus and/or dyslipidaemia could achieve significant changes in the reduction of biochemical and haemodynamic risk parameters. PATIENTS AND METHODS The study included 320 women aged between 45 and 60 years old who were diagnosed with hypertension, diabetes mellitus and/or dyslipidaemia. They were randomly assigned to the experimental group (n=160) and the control group (n=160). The intervention group received three educational sessions and the control group received an informative leaflet sent by mail. Haemodynamic and biochemical variables were evaluated at baseline and one year later in both groups. RESULTS Women in the intervention group showed a decrease in low density lipoprotein (P=.034), (-5.89±29.8; 95% CI: -13.1/0.27) and an increase in high density lipoprotein (P=.013), (2.71±10.6; 95% CI: -1.36/6.20), as well as improvements in systolic blood pressure (P=.016), (-2.16±11.8; 95% CI: -4.4/0.01) and frequency (P=.003), (-1.46±10.3; 95% CI: -3.34/0.42) compared to women in the control group. Women in the control group significantly increased glucose (P=.04), (4.84±15.5; 95% CI: -0.75/31.3) and gamma-glutamyltranspeptidase (P=.031), (3.61±14.7; 95% CI: 0.87/6.36) levels more than those in the experimental group. CONCLUSIONS An educational intervention can be an effective method of reducing the parameters associated with an increased likelihood of cardiovascular disease in women at perimenopausal age with hypertension, diabetes mellitus and/or dyslipidaemia.
