简要总结
In a population of boys and girls high school basketball players, the primary objectives are to assess 1) bone mineral density and vitamin D status, and 2) energy intake and dietary quality.
The secondary objectives are to assess 1) nutrients related to bone health (calcium, magnesium, vitamin K, protein) and 2) protein intake over the day.
Data collection takes place pre-, mid-, and post-season.
详细描述
This study will assess the dietary intake male and female 14-19 year old student athletes, specifically energy intake and dietary quality (i.e. how closely do their diets meet recommendations).
Investigators hypothesize that vitamin D status will be suboptimal in most participants though bone density will be normal.
Investigators hypothesize that participants will maintain energy balance over the course of the season (no significant changes to body mass or body composition) but dietary quality will not meet recommendations.

结局指标
主要结局
Bone mineral density
时间窗: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Adequacy will be defined as a value > 32 ng/mL. Higher Vitamin D values would be better.
vitamin D status
Energy intake
时间窗: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Energy intake that meets recommendations would be better.
24 hour recall
Dietary quality
时间窗: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Diet quality that meets recommendations would be better.

次要结局
- Assess nutrients related to bone health (vitamin K)(Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Vitamin K intake that meets recommendations would be better.)
- Assess nutrients related to bone health (calcium)(Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Calcium intake that meets recommendations would be better.)
- Assess nutrients related to bone health (magnesium)(Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Magnesium intake that meets recommendations would be better.)
- Assess nutrients related to bone health (protein)(Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Protein intake that meets recommendations would be better.)
- Protein intake over the day(Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Looking at pattern of protein intake.)
