# Adult Weight, Genetics and Lifestyle Factors

**Official Title:** The Influence of Nutrition, Childhood and Adult Lifestyle Factors and Genetic Predisposition on Body Mass Index

**NCT ID:** [NCT03666156](https://clinicaltrials.gov/study/NCT03666156)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 96
- **Lead Sponsor:** St Mary's University College
- **Conditions:** Obesity
- **Start Date:** 2018-09-01

## Brief Summary

Childhood obesity leads to adulthood obesity, demonstrated in many retrospective and longitudinal studies. Genetics as a predictor of obesity is less established. Morandi et al, (2012) assessed whether lifestyle and genetic factors can be used to predict childhood obesity, concluding that genetics had minimal predictive effect. More recently Seyednasrollah, (2017) demonstrated that genetic information, when alongside clinical factors for cardiovascular disease, increased the predictive accuracy of obesity risk in adults. This study aims to investigate if known lifestyle and genetic risk factors are associated with BMI and if they can be used as predictors of overweight/obesity in adults.
