The systematic development of guidance for parents on talking to children of primary school age about weight.

Background: The prevalence of overweight and obesity in children is increasing, alongside increases in rates of children's anxiety and worry about their weight. In many countries children's weight is measured, and parents are made aware if a child has been classified as having overweight or obesity. However, many parents are concerned that raising their child's awareness of their weight, and talking to children about their weight could harm their wellbeing.

The acceptability of evidence-informed guidance for parents in talking to their children about weight.

Background: Many parents express concern about the impact of talking to children about weight on their self-esteem and wellbeing. The aim of this study was to explore the perceived relevance, utility and acceptability of new guidance for parents on talking to children about weight, developed to apply theory, evidence and expert advice into practice.

Methods: For this qualitative study, parents and public health practitioners (PHPs) were recruited from ten local authorities in England, through the National Child Measurement Programme between June and September 2021.

Association Between Patient Factors and the Effectiveness of Wearable Trackers at Increasing the Number of Steps per Day Among Adults With Cardiometabolic Conditions: Meta-analysis of Individual Patient Data From Randomized Controlled Trials.

Background: Current evidence supports the use of wearable trackers by people with cardiometabolic conditions. However, as the health benefits are small and confounded by heterogeneity, there remains uncertainty as to which patient groups are most helped by wearable trackers.

Objective: This study examined the effects of wearable trackers in patients with cardiometabolic conditions to identify subgroups of patients who most benefited and to understand interventional differences.

Does adjusting for biological maturity when calculating child weight status improve the accuracy of predicting future health risk?

Background: The aim of this study was to assess whether adjusting the weight categorisation of children for their biological maturity status could improve the accuracy of predicting weight status and cardiometabolic risk at age 17.

Methods: Data from 1525 participants (787 female) from the ALSPAC study were analysed. Participants' weight status at age 11 was estimated using first standard chronological age and sex adjusted BMI cut-offs, and again using maturity adjusted BMI cut-offs.

Influence of obesity prevalence on social norms and weight control motivation: a cross-sectional comparison of the Netherlands and the UK.

This cross-sectional survey study explored associations between perceived bodyweight norms, psychological need satisfaction and motivation for weight control among 500 adult residents of two countries with different overweight/obesity prevalence: the UK (63% prevalence) and the Netherlands (50%). A hypothesised model of the effects of descriptive norms (i.e.

Effects of a Web-Based, Evolutionary Mismatch-Framed Intervention Targeting Physical Activity and Diet: a Randomised Controlled Trial.

Background: This study sought to test the effectiveness of a 12-week, novel online intervention (Evolife) aiming to increase physical activity level (PAL) and reduce energy intake (EI) among overweight/obese adults. The intervention used an evolutionary mismatch message to frame health information in an engaging way, incorporating evidence-based behaviour change techniques to promote autonomous motivation, self-efficacy and self-regulatory skills.

Method: Men and women aged 35-74 years with a BMI of 25-40 kg/m were eligible.
