The problem
Intervention: Observational assessment of parent-child dietary concordance through questionnaires measuring Mediterranean Diet adherence (MEDAS for parents, KIDMED for children) and fast-food consumption frequency
Who it was tested with: 85 parent-child dyads from two Portuguese basic education schools.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"This cross-sectional study included 85 parent/guardian-child dyads recruited by convenience from two Portuguese basic education schools. Parents/guardians completed an online questionnaire for themselves and their child. Mediterranean Diet adherence was assessed using MEDAS and KIDMED. Associations were examined using Spearman correlations with bootstrap 95% confidence intervals." This is an observational study measuring associations between parental and child dietary patterns without intervention or causal manipulation.
Convenience sample of only 85 dyads from two schools limits generalisability. Self-reported dietary data is subject to recall and social desirability bias. Cross-sectional design cannot determine causality or direction of influence. No direct dietary assessment (e.g. food diaries, biomarkers).
