Objective:

To identify and analyze from a quantitative / qualitative perspective the socioeconomic indicators of maternal obesity in Mexico.

Methods and material:

Evaluative research based on a prospective / analytical cohort design. The sample size was established by all the women who came to the antenatal clinic from the 24th week of gestation in a state referral hospital. The sample size was estimated with 80% power and 95% confidence and significance. The indicators of interest were socioeconomic aspects, nutrition, anthropometry, diet, food safety and physical activity. The quantitative analysis was performed using the Stata version 14 software and the qualitative analysis with Atlas-ti version 8.0.

Results:

The cohort was comprised of 402 pregnant women in 2017. From the main results we found that 55% of the women were in the age range of 18-24 years; 15% of women reported having a paid job; 42% of the population had full secondary education; 32.1% presented a degree of food insecurity; the mean BMI was 27.8 ± 4.8, 48% of the women were overweight and obese.

Conclusions:

Quantitative results suggest that populations with greater socio-economic vulnerability, food insecurity and low physical activity are more prone to maternal obesity. The qualitative results, besides complementing and reinforcing the quantitative results, present evidence to identify in greater detail the barriers and facilitators to strengthen intervention programs in the prevention of maternal obesity.
