Brief summary
The aim of the SuNDiAL 2020 project is to describe the nutritional status, dietary habits, health status, attitudes and motivations for food choice, 24 h activity patterns and screen time of adolescent boys. There is very limited data about dietary intake and lifestyles of this age group. At least 150 males aged between 15 and 18 years will be recruited to participate from secondary schools throughout New Zealand between February 2020 and November 2020. Participants will complete two 24-hour diet recalls to provide an estimate of usual dietary intake, provide a blood sample for the analysis of biochemical status of cholesterol concentrations and HbA1c, have their blood pressure measured, have their height, weight, and ulna length measured, provide a urine sample to allow assessment of iodine intake, perform two previous day activity recalls and wear an accelerometer for 7 days to provide an estimate of 24-hour activity (sleep, sedentary behavior, screen time and physical activity), and answer questions about their attitudes and beliefs about the foods they choose to eat (or not eat) their dietary habits and screen time. Results will be used to inform public health policy about appropriate ways to encourage healthy lifestyles in this age group.
Interventions
Participants will complete two 24-h diet recalls (retrospective recall of diet; each taking approximately 30 min to complete) to provide an estimate of usual dietary intake (the first of these recalls will be performed on a school day, the second will be performed on a Saturday or Sunday, no more than 2 weeks after the first recall). They will also complete two previous day activity recalls (retrospective recall of activity, including sleep, physical activity, sedentary time and screen use; eac
Participants will complete two 24-h diet recalls (retrospective recall of diet; each taking approximately 30 min to complete) to provide an estimate of usual dietary intake (the first of these recalls will be performed on a school day, the second will be performed on a Saturday or Sunday, no more than 2 weeks after the first recall). They will also complete two previous day activity recalls (retrospective recall of activity, including sleep, physical activity, sedentary time and screen use; each taking approximately 30 min to complete). Participants will also provide a blood sample for analysis of lipid and HbA1c concentrations, a urine sample for analysis of iodine concentrations (5 min)wear an accelerometer for 7 days to provide an estimate of 24 h activity (sleep, sedentary behavior and physical activity) and answer questions about their attitudes and beliefs about the foods they choose to eat (or not eat) All these components will be measured over a two week time period. Data collection will occur in two distinct time periods so participants will either undergo data collection procedures between February and April 2020 or August and October 2020
