Parental obesity is a known risk factor for childhood obesity though the literature is less clear whether there are differences in associations in weight according to parental gender and child gender. Overweight children are more likely to become overweight adults, with the associated socioeconomic and health related consequences presenting a major public health challenge. Within the 34 Organisation for Economic Cooperation and Development (OECD) countries, the UK is ranked 9th for childhood overweight prevalence In England, the National Child Measurement Programme (NCMP) assesses weight status in Reception (aged 4–5 years) and Year 6 (aged 10–11 years) of primary school and local analyses have shown a rise in child BMI z-score between these ages. The global prevalence of overweight and obese children has risen in the past four decades from 4% in 1975 to 18% in 2016. Further studies are needed to explore the impact of parental weight change on child BMI z-score and whether interventions targeted at overweight or obese parents, can improve their child’s BMI z-score. The key indicator of higher child BMI at Year 4 is high BMI at Year 1. Parental BMI change was not significantly associated with Year 4 child BMI z-score. For every unit increase in parent BMI, there was an increase in child BMI z-score of 0.047 in Year 1 ( p = < 0.005) and of 0.059 in Year 4 ( p = < 0.005). Child mean BMI z-score score increased from 0.198 to 0.330 ( p = < 0.005) between these timepoints. There was a strong association between child BMI z-score at Year 1 and 4. The influence of change in parental BMI between Year 1 and Year 4 on child BMI z-score in Year 4 was explored through regression analyses, adjusted for baseline BMI z-score. Multivariable linear regression models examined the cross-sectional associations between child BMI z-score and parent BMI in Year 1 and 4. A paired sample t-test examined changes in child BMI z-score between Year 1 and 4. Methodsĭata from the longitudinal B-ProAct1v study (1837 participants) were analysed. This is important to understand for the development of effective obesity interventions. Persons may consider seeking advice from their health-care providers on healthy weight status and to consider individual circumstances.This paper aims to explore change in BMI z-score through childhood and the association between parent BMI and child BMI z-score. Individuals with the same BMI may have different amounts of body fat. Since BMI is based on weight and height, it is only an indicator of body fatness. Please keep in mind that this BMI calculator is not meant to serve as a source of clinical guidance and is not intended to be a substitute for professional medical advice. If your child has significant weight loss or gain he or she should be referred to and guided by a health professional. A single BMI-for-age calculation is not enough to evaluate long-term weight status because height and weight change with growth. Tracking growth patterns over time can help you make sure your child is achieving or maintaining a healthy weight. It displays numeric results, a graphic that shows the weight category, and plots the BMI on a printable growth chart.Ĭheck BMI-for-age annually, or more often if recommended by the child’s healthcare provider. CDC has an online tool to calculate BMI for kids and teens (age 2 through 19).
