Development, validity and reliability of a questionnaire to measure children’s psychosocial factors related to healthy meal preparation

Culinary Nutrition Education Improves Home Food Availability and Psychosocial Factors Related to Healthy Meal Preparation Among Children

OBJECTIVE

To evaluate the effectiveness of a culinary nutrition education intervention on children's home food availability and psychosocial factors related to healthy meal preparation.

DESIGN

Randomized-controlled trial.

SETTING

Schools in Kuala Lumpur, Malaysia.

PARTICIPANTS

Eighty-three school children aged 10-11 years and their parents.

INTERVENTION

Twelve weeks of culinary nutrition education with 5 hands-on healthy meal preparation modules and a module with parents on home food availability (conducted every 2 weeks).

MAIN OUTCOME MEASURES

Psychosocial factors (knowledge, attitude, practice, and self-efficacy) related to healthy meal preparation and home food availability (fruits, vegetables, healthful foods, and less healthful foods) assessed via children and parents, respectively, using validated questionnaires at baseline, postintervention, and 3-month follow-up.

ANALYSIS

Repeated measures ANOVA.

RESULTS

Intervention group had a higher (P < 0.001) mean knowledge score (mean difference, 1.2), attitude (mean difference, 2.6), practice (mean difference, 4.4) and self-efficacy (mean difference, 3.9) of healthy meal preparation as compared with control group across 3-time points. Improvements were seen in the availability of fruits (mean difference, 3.0; P < 0.001), vegetables (mean difference, 2.4; P < 0.001), healthful foods (mean difference, 1.5; P < 0.001) and less healthful foods (mean difference, -0.9; P = 0.001), favoring the intervention group.

CONCLUSION AND IMPLICATIONS

Culinary nutrition education had positive impact on children's psychosocial factors and home food availability, demonstrating the potential to improve children's nutrition.

Influences of psychosocial factors and home food availability on healthy meal preparation

The involvement of children in healthy meal preparation activities has emerged as a potential strategy to promote healthy eating behaviour among children. However, there is a lack of understanding of children's internal (psychosocial factors) and external factors (home food availability) that may support the practice of preparing healthy meals. This study aimed to determine children's psychosocial factors of healthy meal preparation within themselves and their external environment of home food availability as predictors for the practice of healthy meal preparation. Public schools (n = 8) from all three zones (Bangsar-Pudu, Keramat and Sentul) in Kuala Lumpur, Malaysia, were selected through stratified random sampling. Two hundred children aged 9-11 and their parents participated. Children's psychosocial factors towards healthy meal preparation and their home food availability were assessed through children and parents, respectively, using validated questionnaires. Majority of the schoolchildren (86.5%) had poor practice of healthy meal preparation. Increased attitude (r = 0.344, P < 0.001) and self-efficacy (r = 0.501, P < 0.001) of healthy meal preparation and the availability of fruits (r = 0.304, P < 0.001), vegetables (r = 0.243, P < 0.001) and healthful ready-to-eat foods (r = 0.227, P = 0.001) at home were positively correlated with the practice of preparing healthy meals. After adjusting for age, sex and monthly household income, increased self-efficacy (P < 0.001), availability of fruits (P = 0.01) and lower availability of less healthful ready-to-eat food (P = 0.01) were associated with better healthy meal preparation practices. Outcomes revealed that positive self-efficacy of healthy meal preparation, home food availability of fruits and less healthful alternatives were associated with the practice of healthy meal preparation and thus should be targeted in future health-promotion strategy.

Children's psychosocial factors of healthy meal preparation as predictors for nutritional status measures

Involving school-age children in the preparation of healthy meals is shown to be associated with positive eating behavior. Yet, it remains unclear whether this can extend to their nutritional status. The present study aimed to determine the association of school-age children's psychosocial factors (knowledge, attitude, practice, self-efficacy) towards healthy meal preparation with their nutritional status (BMI-for-age, waist circumference, body fat percentage). Stratified random sampling was used to select primary schools (n = 8) in Kuala Lumpur, Malaysia. Two hundred school children aged between 9-11 years old were involved. Psychosocial factors towards healthy meal preparation were assessed using validated questionnaire. Anthropometry measures were determined using standard protocol. Almost half (46 %) of the school-age children were obese/overweight, 39 % were abdominally obese and 40 % were overfat. Approximately half had poor knowledge (49 %), poor practice (45 %), good attitude (56 %) and good self-efficacy (47 %) towards healthy meal preparation. Significant positive correlations were observed between knowledge with attitude (r = 0.23, p < 0.001); knowledge with self-efficacy (r = 0.30, p < 0.001); attitude with practice (r = 0.34, p < 0.001); attitude with self-efficacy (r = 0.59, p < 0.001) and practice with self-efficacy (r = 0.50, p < 0.001). Adjusted logistic regression revealed that school-age children with good attitude were less likely to be abdominally obese (OR = 0.87, 95 % Cl = 0.78 to 0.96) and overfat (OR = 0.84, 95 % Cl = 0.76 to 0.94). Children with good knowledge had lower risk of being abdominally obese (OR = 0.84, 95 % Cl = 0.72 to 0.97). Findings revealed that children's psychosocial factors were interrelated, and improvements may have the potential in affecting nutritional status. Hands-on healthy meal preparation should be explored further as an innovative approach to address the obesity epidemic.
