Nutritional status can affect the linear growth of bones during puberty by affecting growth plate (GP) chondrocytes. We hypothesized that there is a relationship between dietary patterns and bone age on girls who have experienced height loss. This cross-sectional study was conducted on 350 girls aged 12-13 years with open GP, and major dietary patterns were determined using the factor analysis method. Dual-energy x-ray absorptiometry measurement of participant’s wrist was performed to determine GP openness and bone age. In the present study, 70.3% of participants had bone age below chronological age. Three major dietary patterns—healthy, high sugar and salt, and Western diet—were identified using findings of dietary intake. Adherence to the healthy diet led to significant increase in height, weight, body mass index, and other components of body composition such as lean body mass (P < .001). Among these dietary patterns, we found only a significant association between healthy diet and difference between bone and chronological age (B = –0.106). In the present study, adherence to a healthy diet was associated with increase in bone age (P = .02). Healthy dietary pattern with an emphasis on enough intake of plant protein and white meat was associated with better linear growth.
