KUZMAR, Isaac; CORTES, Ernesto  e  RIZO, Mercedes. Age group, menarche and regularity of menstrual cycles as efficiency predictors in the treatment of overweight. Nutr. Hosp. [online]. 2015, vol.31, n.2, pp.637-641. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2015.31.2.7501.

Objective: To evaluate if there is a relation between age groups, menarche, menstrual cycles and previous pregnancies with the success of weight loss in obese patients at a nutrition clinic. Methods: A clinical intervention study was conducted among overweight and obese patients who consulted a nutrition clinic in Barranquilla (Colombia) for the purpose of nutritional assessment. They were subject to a personalized weekly follow-up consultation over the course of 16 weeks in which food consumption patterns, anthropometric measures, body image and self-perception were registered. Results: A total of 135 patients were evaluated. 41 (30,4%) of whom did not complete the study. 69,6% patients did lose weight and 83,7% did lose waist. These losses are lower in older ages (95,5% at <18y vs. 56,4% in > 45y, p=0,0085), not varying between overweight and obesity. There are significant losses in the final BMI (2,2(1,5SD) kg/m² in <18years group vs. 1,1(0,7SD) kg/ m² in >45years group; p=0,009), weight loss percentage (7,3(4,3SD)% vs. 3,8(2,1SD)%, p=0,013), waist loss percentage (8,8(4,1SD)% vs. 5,8(2.5SD)%, p=0,005) and hip loss percentage (5,4(3,8SD)% vs. 3,5(2,6SD)%, p=0,040). Age influence is confirmed by multivariate analysis with no considerable differences observed in relation to menarche, menstrual cycle regularity and previous pregnancy in success distribution. Influence of initial BMI is >5% among obese women, with an OR=3,9 (1,2 to 12,8, 95% CI) (p=0,026). Conclusion: Based on these results, age groups and initial BMI are regarded as influential factors in the successful outcome of treatment in overweight and obese patients.
