Association between dietary phytochemical index and 3-year changes in weight, waist circumference and body adiposity index in adults: Tehran Lipid and Glucose study

Table 6 The association between dietary phytochemical index at baseline and 3-year change in anthropometric measures ¹

¹Data are β regression and 95% confidence interval were estimated by using multiple regression models with adjustment for sex, age at baseline (y, continuous), BMI (kg/m², continuous), education (4 categories), smoking (yes or no), physical activity (MET-h/wk, continuous), total energy intake (kcal/d), dietary carbohydrate (% of energy), fat (% of energy) and protein (% of energy).
²A linear trend test was performed by considering each ordinal score variable as a continuous variable in the model.
Medians of dietary phytochemical index quartiles were 17.3, 24.9, 31.8, and 41 in the first1, 2, 3 and 4^th quartile categories, respectively.
