Eating behavior of parents plays key role in child’s emotional eating

Emotional eating, or eating as a coping mechanism for negative, positive, or stress-driven emotions, is associated with unhealthy dietary patterns and weight gain. A research article featured in the Journal of Nutrition Education and Behavior, published by Elsevier, discusses adolescent vulnerability to emotional eating and how various feeding practices used by parents, such as restriction, food as reward, and child involvement, influence eating behavior.

“Emotional eating was previously found to be more learned than inherited. This study examined not only the interaction between parents when feeding their children, but also what children learned from watching their parents eat,” said lead author Joanna Klosowska, MSc, Department of Public Health and Primary Care, Ghent University, Ghent, Belgium.

Over the four years between 2013 −2017, covering the time from late childhood to middle adolescence, changes occurred in some parental practices. Parents reported higher monitoring and healthy modeling feeding practices, while the reported levels of food restriction and the healthy environment remained unchanged. During the same time period, adolescents reported a considerable increase in emotional eating from below the average in 2013 to above the average in 2017, according to the norms for the Dutch population. Additionally, the maladaptive way in which they regulated their emotions was also associated with emotional eating.

Food as a reward and monitoring food increased emotional eating especially in instances where the adolescent employed maladaptive strategies in regulating their emotions. Child involvement in meals had an opposite effect since it was associated with higher levels of emotion regulation and lower levels of emotional eating. Interestingly, a parent’s restrained eating behavior was linked to less emotional eating in adolescents.

“This study suggests that parents continue to play an important role in their child’s eating behavior into their teen years,” said Klosowska. “Additional research is needed to understand the impact restrained eating demonstrated by a parent impacts the emotional eating of a child.”

 

Insufficient sleep in teenagers leads to obesity: Study

Adolescents who sleep less than eight hours a night are more likely to be overweight or obese compared to their peers with sufficient sleep, said a new study presented at ESC Congress 2022.

Shorter sleepers were also more likely to have a combination of other unhealthy characteristics including excess fat around the middle, elevated blood pressure, and abnormal blood lipid and glucose levels, said the study by Jesús Martínez Gómez, a researcher at the Cardiovascular Health and Imaging Laboratory, Spanish National Centre for Cardiovascular Research (CNIC), Madrid, Spain.

“Our study shows that most teenagers do not get enough sleep and this is connected with excess weight and characteristics that promote weight gain, potentially setting them up for future problems,” said study author Gómez. “We are currently investigating whether poor sleep habits are related to excessive screen time, which could explain why older adolescents get even less sleep than younger ones.”

This study examined the association between sleep duration and health in 1,229 adolescents in the SI! Program for Secondary Schools trial in Spain. Participants had an average age of 12 years at baseline with equal numbers of boys and girls.

Sleep was measured for seven days with a wearable activity tracker three times in each participant at ages 12, 14 and 16 years. For optimal health, the American Academy of Sleep Medicine advises sleeping 9 to 12 hours a night for 6 to 12 year-olds and 8 to 10 hours for 13 to 18 year-olds.To simplify the analysis, the study used 8 hours or more as optimal. Participants were categorized as very short sleepers (less than 7 hours), short sleepers (7 to 8 hours), and optimal (8 hours or more).

Overweight and obesity were determined according to body mass index. The researchers calculated a continuous metabolic syndrome score ranging from negative (healthier) to positive (unhealthier) values that included waist circumference, blood pressure, and blood glucose and lipid levels.

At 12 years of age, only 34% of participants slept at least 8 hours a night, and this dropped to 23% and 19% at 14 and 16 years of age, respectively. Boys tended to get less sleep. Teenagers who got the most sleep also had better quality sleep, meaning they woke up less during the night and spent a higher proportion of the time in bed sleeping compared to those with shorter sleep. The prevalence of overweight/obesity was 27%, 24% and 21% at 12, 14 and 16 years of age, respectively.

Compared with optimal sleepers, overweight/obesity was 21% and 72% more likely in very short sleepers at 12 and 14 years, respectively. Short sleepers were 19% and 29% more likely to be overweight/obese compared with optimal sleepers at 12 and 14 years, respectively. Similarly, both very short and short sleepers had higher average metabolic syndrome scores at 12 and 14 years compared with optimal sleepers.

Mr. Martínez Gómez said: “The connections between insufficient sleep and adverse health were independent of energy intake and physical activity levels, indicating that sleep itself is important.”

Deny teenagers any screen, they’ll soon go to sleep: Study

Sleep in teenagers can be improved by just one week of limiting their evening exposure to light-emitting screens on phones, tablets and computers, said a study whose findings will be presented in Lyon, at the European Society of Endocrinology annual meeting, ECE 2019.

The study indicates that by simply limiting their exposure to blue-light emitting devices in the evening, adolescents can improve their sleep quality and reduce symptoms of fatigue, lack of concentration and bad mood, after just one week.

Recent studies have indicated that exposure to too much evening light, particularly the blue light emitted from screens on smartphones, tablets and computers can affect the brain’s clock and the production of the sleep hormone melatonin, resulting in disrupted sleep time and quality.

The lack of sleep doesn’t just cause immediate symptoms of tiredness and poor concentration but can also increase the risk of more serious long-term health issues such as obesity, diabetes and heart disease. Other studies have suggested that sleep deprivation related to screen time may affect children and adolescents more than adults, but no studies have fully investigated how real-life exposure is affecting sleep in adolescents at home and whether it can be reversed.

In this collaborative study between the Netherlands Institute of Neuroscience, the Amsterdam UMC and the Dutch National Institute for Public Health and the Environment, researchers investigated the effects of blue light exposure on adolescents at home. Those who had more than 4 hours per day of screen time had on average 30 minutes later sleep onset and wake up times than those who recorded less than 1 hour per day of screen time, as well as more symptoms of sleep loss.

The team conducted a randomised controlled trial to assess the effects of blocking blue light with glasses and no screen time during the evening on the sleep pattern of 25 frequent users. Both blocking blue light with glasses and screen abstinence resulted in sleep onset and wake up times occurring 20 minutes earlier, and a reduction in reported symptoms of sleep loss in participants, after just one week.

Dr Dirk Jan Stenvers from the department of Endocrinology and Metabolism of the Amsterdam UMC says, “Adolescents increasingly spend more time on devices with screens and sleep complaints are frequent in this age group. Here we show very simply that these sleep complaints can be easily reversed by minimising evening screen use or exposure to blue light. Based on our data, it is likely that adolescent sleep complaints and delayed sleep onset are at least partly mediated by blue light from screens”

Dr Stenvers and his colleagues are now interested in whether the relationship between reduced screen time and improved sleep has longer lasting effects, and whether the same effects can be detected in adults.

Dr Stenvers comments, “Sleep disturbances start with minor symptoms of tiredness and poor concentration but in the long-term we know that sleep loss is associated with increased risk of obesity, diabetes and heart disease. If we can introduce simple measures now to tackle this issue, we can avoid greater health problems in years to come.”
