OBJECTIVETo determine the frequency of FFN in adults from a primary care unit in Michoacán and its relation cardiometabolic risk factors.SETTINGUnidad de Medicina Familiar No. 80, Morelia. Mich., México.DESIGNObservational, retrospective, cross-sectional, and analytical.PARTICIPANTThree hundred twenty-fiveparticipants aged 19 years and older.EVALUATIONSAnthropometric measurements, fasting blood glucose, triglycerides, cholesterol, and HDL cholesterol levels were evaluated. The Childhood Family Strengths Questionnaire was utilized. FFN questionnaire was used and a protective (≥5) or non-protective (<5) score was assigned to each participant. Descriptive statistics, Chi-square tests, and logistic regression analysis were performed.RESULTSThe 61.4% of the sample reported a protective score in the FFN questionnaire. The non- protective FFN score was associated with an increased risk of chronic disease and systemic arterial hypertension. In women, an association was observed between FFN and fasting hyperglycemia and metabolic syndrome; while in men, there was an association of FFN with diabetes diagnosis, increased triglycerides levels and low education level.CONCLUSIONSA non- protective FFN score increased cardiometabolic risk in adulthood in a gender-dependent way. These findings highlight the importance of considering early childhood experiences as determinants of long-term health and emphasize the need for a gender perspective in their analysis.
