Serum 25-hydroxyvitamin D level in relation to weight change and the risk of weight gain in adults of normal weight at baseline: the Norwegian HUNT cohort study.

ABSTRACT:

Objective

We sought to investigate the relationship of serum 25-hydroxyvitamin D (25(OH)D) level with weight change and the risk of weight gain in an adult population who had normal weight at baseline and were followed up for 11 years.

Design

A population-based prospective cohort study.

Setting

Nord-Trøndelag, Norway.

Participants

The study included 1501 adults who participated in the second and third surveys of the Nord-Trøndelag Health Study (HUNT2 (1995-1997) and HUNT3 (2006-2008)) and had a normal body mass index ≥18.5 and <25.0 kg/m² at baseline.

Primary and secondary outcome measures

Relative weight change (%) was calculated as ((HUNT3 weight-HUNT2 weight)/HUNT2 weight×100). Relative annual weight change (%) was calculated as (relative w
