  1. Rate of weight gain, weight fluctuation, and incidence of NIDDM.

    Article - En anglais

    The relationships of rate of weight gain and weight fluctuation to incidence of non-insulin-dependent diabetes mellitus (NIDDM) were examined in Pima Indians.

    The 1,458 subjects were participants in a prospective study with examinations approximately every 2 years.

    Rate of weight gain was defined as the slope of the regression line of weight with time for two or more consecutive examinations =2 years apart and weight fluctuation as the root-mean-square departure from this line for four examinations.

    Among men, incidence of NIDDM was strongly and significantly related to rate of weight gain (e.g., age-adjusted incidence=56.7/1,000 person-years in those with weight gain =3 kg/year and 16.9/1,000 person-years for those losing weight [Ptrend<0.01]). In women, weight gain was significantly related to diabetes incidence only in those who were not initially overweight (body mass index<27.3 KG/M2).

    In contrast to the relationship with weight gain, weight fluctuation was not associated with incidence of diabetes in either sex.

    These findings suggest that weight control in overweight individuals may be a more effective strategy for prevention of NIDDM in men than in women, whereas prevention of obesity may prevent diabetes in both sexes.

    Concern about a diabetogenic effect of weight fluctuation should not deter weight-control efforts.
