March 19, 2026 updated by: Claudia Teresa Tovar Palacio

Family-based Intervention Model to Prevent Childhood Obesity Among Schoolage Children in Sonora, Mexico.

This proposal aims to enhance the well being of schoolchildren and their families through a mobile application and multidisciplinary intervention model grounded in authoritative parenting principles and social cognitive theory.

Detailed Description

Childhood is recognized as a critical period of metabolic sensitivity, during which excess adiposity increases the likelihood of developing metabolic abnormalities in adulthood by approximately 70%, including hypertension, dyslipidemia, insulin resistance, hyperuricemia, and non-alcoholic fatty liver disease. In Mexico, overweight and obesity affect 35.5% of school-aged children, inevitably contributing to the growing prevalence of non-communicable chronic diseases. Data from ENSANUT 2018 place Sonora among the five states with the highest rates of obesity, with 22.2% of adolescents aged 12-19 years classified as obese. This epidemiological context highlights the pressing need for innovative strategies to promote prevention and early risk detection during childhood.

Evidence indicates that mobile health (mHealth) applications may effectively reduce body weight and prevent fat accumulation. Nevertheless, only a limited number of studies have applied mHealth interventions to prevent pediatric adiposity or to foster behavioral changes in comparison with conventional nutritional approaches. The proposed model incorporates a communication strategy designed to monitor participant needs, offer engagement incentives, and promote adherence to the study protocol.

The primary research question addresses whether a family-focused intervention can effectively improve eating patterns and food-related behaviors among students enrolled at "La Caridad" Educational Center in Nacozari de García, Sonora.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dietary behavior
Time Frame: Six months
The Children's Eating Behavior Questionnaire (CEBQ) will be administered. The responses will be scored and interpreted using standardized scales, yielding two main dimensions: overeating-related behaviors (where higher scores indicate increased risk of obesity) and undereating-related behaviors (where higher scores suggest risk of underweight or feeding difficulties). Each dimension is further divided into four subscales, allowing for a more detailed characterization of eating behavior patterns.
Six months
Body index mass
Time Frame: Six months
Measured in Kg/m2
Six months
Age
Time Frame: Six months
Years lived reported by parents through medical records
Six months
Feeding practices
Time Frame: Six months
Comprehensive Feeding Practices Questionnaire (CFPQ). The CFPQ evaluates parental feeding behaviors across two primary domains, each comprising six subscales. The first domain encompasses health-promoting feeding practices (e.g., modeling, monitoring), while the second includes negative or problematic feeding practices (e.g., use of food as a reward, restrictive practices). Higher scores in health-promoting practices are positively associated with healthier dietary patterns in children. In contrast, higher scores in negative practices are linked to an increased risk of pediatric obesity and disordered eating behaviors.
Six months
Body weight
Time Frame: Six months
The total body weight (kg) observed in the intervention group versus the control group.
Six months
Phisical activity
Time Frame: Six months
This questionnaire assesses children's average physical activity (expressed in MET-minutes per week) and sedentary time (in hours/day) across weekdays
Six months
Height
Time Frame: Six months
Mean values of anthropometric measurements obtained using a stadiometer, expressed in centimeters.
Six months
Fat mass
Time Frame: Six months
Children's fat mass, as determined by bioelectrical impedance analysis, will be expressed as a percentage (%).
Six months
Fat-free mass
Time Frame: Six months
Children's fat-free mass, as determined by bioelectrical impedance analysis, will be expressed as a percentage (%).
Six months
Glucose
Time Frame: Six months
Change in glucose concentration will be determined by measuring capillary blood glucose levels (mg/dL)
Six months
Triacylglycerides
Time Frame: Six months
Changes in triacylglycerol concentration will be determined by measuring capillary blood triacylglycerol levels (mg/dL)
Six months
Total cholesterol
Time Frame: Six months
Changes in total cholesterol concentration will be determined by measuring capillary blood cholesterol levels (mg/dL).
Six months
HDL-Cholesterol
Time Frame: Six months
Changes in HDL-cholesterol concentration will be determined by measuring capillary blood HDL-cholesterol levels (mg/dL).
Six months
LDL-cholesterol
Time Frame: Six months
Changes in LDL-cholesterol concentration will be determined by measuring capillary blood LDL-cholesterol levels.
Six months
Parenting practices
Time Frame: Six months

The Short Parenting Practices Questionnaire is designed to identify and classify parenting styles based on two primary dimensions: warmth (affection) and control (discipline).

In its abbreviated version, the questionnaire asks parents/caregivers to report on items that explore:

Authoritative practices: characterized by high warmth and high control, reflected in behaviors such as providing explanations, setting clear rules, showing affection, and promoting autonomy within appropriate limits.

Authoritarian practices: characterized by low warmth and high control, reflected in behaviors such as rigid discipline, imposing rules without dialogue, and lower expression of affection.

In general, the questionnaire requires self-reported responses regarding the frequency with which parents engage in specific behaviors or strategies in everyday life. These responses are then grouped into the two empirically validated categories.

Six months
Dietary patterns
Time Frame: Six month
Using data collected from a food frequency questionnaire (FFQ) and a 24-hour dietary recall will be evaluated for dietary patterns

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

  1. - BMI for age: ≤-3SD is equivalent to severe thinness, ≤-2 is equivalent to thinness, ≥+2 is equivalent to obesity and ≥+1 is equivalent to overweight
  2. - Height for age: ≥ -1 is equivalent to normal, ≥-2 to ≤ -1 is equivalent to moderately stunted and ≤ -2 is equivalent to severely stunted
