Nutritional quality of children's school lunches: differences according to food source.

Objective: To assess the nutritional quality of lunchtime food consumption among elementary-school children on Prince Edward Island according to the source of food consumed (home v. school).

Design: Students completed a lunchtime food record during an in-class survey.

Implementing elementary school nutrition policy: principals' perspectives.

Purpose: We assessed principals' perceptions about the level of school nutrition policy (SNP) implementation in Prince Edward Island elementary schools, objectively evaluated how closely elementary schools are following SNP regulations for types and frequency of foods offered at school, and explored principals' beliefs about the key enablers and barriers to SNP implementation.

Methods: Phase I involved a cross-sectional survey of principals' assessment of perceived and actual adherence to SNP components. Phase II included in-depth interviews to explore principals' perceptions about factors influencing policy adherence.
