Crowdsourced study finds keys to slim adulthood

by H. Roger Segelken

(Medical Xpress)—Remember that slim kid in school – the one with the cook-from-scratch mom and a large circle of friends? He's likely one of the fittest dudes at your high school reunion.

Or the girl who was bullied – still heavy after all these years and hoping to help modern parents avoid mistakes hers made? People like these readily responded when a crowdsourcing app enabled an international team of nutrition researchers to uncover some surprising "Childhood Predictors of Adult Obesity," published Feb. 5 in the online journal PLOS ONE.

"One of the best safeguards against your children becoming overweight as adults is how involved you are with their lives," says Cornell's Brian Wansink, professor in the Charles H. Dyson School of Applied Economics and Management and a leader of the team that used to ask 532 adults, "Which and behaviors might predict slimness or obesity in adulthood?"

"What's particularly amazing is how people have identified these childhood predictors of obesity that experts never thought about," says Kirsten E. Bevelander, another report author, from The Netherlands' Radboud University Behavioural Science Institute. "Things like bullying, number of friends and how often parents play outdoors with their children are significantly predictive of how much a child will weigh as an adult."

"Playing with your children, talking about nutrition and simply spending time with them will make it more likely that your child becomes a slim adult," adds Wansink, director of the Cornell Food and Brand Lab. "The bottom line for parents is: Spend a lot of time with your kids – it almost doesn't matter what (activity) you do with them – just stay in their young lives."

The study began by recruiting participants from reddit.com, the user-generated content news site, with notices posted on reddit sections for dieting, weight loss and parenting.

Each participant offered what they believed to be the best predictor of what a child would weigh as an adult – home environment, psychosocial well-being, lifestyle, family history – and submitted the predictor in the form of a question. Besides supplying his or her height and weight (to determine , or BMI) and age, participants answered questions generated by other participants about their own childhood behaviors and conditions.

The researchers said their project was among the first to use crowd-sourced information to identify new predictors that may, after further study, be useful in understanding and reducing obesity.

In the paper, the researchers encourage parents to create a "nurturing and healthy and lifestyle for children that includes meals made from scratch, healthy eating conversations, plenty of sleep, outdoor exercise and supporting healthy friendships with peers."

Funding for the study came from Tekes, the Finnish Funding Agency for Technology and Innovation; the National Science Foundation; the Defense Advanced Research Projects Agency; and Cornell University.

Childhood predictors

Adults who reported a lower BMI also reported having the following childhood experiences in common:

  • Their families prepared meals using fresh ingredients.
  • Their parents talked with them about nutrition.
  • They frequently engaged in outdoor physical activity with their families.
  • They slept a healthy number of hours on weeknights.
  • They had many friends.

Adults who reported a higher BMI, also reported having the following childhood experiences in common:

  • Food was used as a reward or punishment at home.
  • They had obese parents and/or grandparents.
  • They drank juice and soda more than water.
  • Their restricted their food intake.
  • They were bullied by peers.
