Evaluation of the relationship between the frequency of attention deficit, hyperactivity disorder symptoms and nutritional habits in children.

Abstract

Introduction: Attention deficit and hyperactivity disorder (ADHD) is a common chronic neurodevelopment disorder characterised by inattention, hyperactivity and impulsivity at levels that are not compatible with age. ADHD is one of the high social and individual costs for the population of the country. In the present study, it was aimed to investigate the relationship between some sociodemographic characteristics, nutrition and sleep patterns, certain habits and various factors with ADHD in primary school children aged between 6 to 10 years.

Materials and methods: In the study, a total of 600 children's parents were asked to fill in the Conners Parent Rating Scale - Short Form (CPRS-48), which consists of 48 questions. The questions in the scale are answered by the parents on a four-point Likert scale. The responses were scored as 0, 1, 2 and 3 for 'never', 'rarely', 'often' and 'always', respectively. It was accepted that the children who scored at least 18 for the behaviour problem subscale, at least five for the learning problem subscale, at least six for the aggression, hyperactivity subscale, and at least seven for the defying subscale were considered to be in the problematic category. In order to determine the eating habits of the children included in the study, their parents filled out the food consumption frequency form. Foods in the form of food consumption frequency are divided into two groups as healthy and unhealthy foods. Individuals were given scores between 0 and 6 according to the frequency of food consumption. The healthy food group and unhealthy food group scores were collected separately.

Results: Of the children included in the study, 312 (52%) were male, with a mean age of 8.24±1.30 (range: 6 10) years. The mean CPRS-48 score was 23.88±19.71. The Cronbach's Alpha value of the CPRS-48 scale, which consists of 48 questions in total, was obtained as 0.957. The mean CPRS-48 score was significantly higher in boys (p = 0.014), in those whose mothers smoked during pregnancy (p = 0.008), those who did not receive breast feeding at birth or those who received less than 2 months (p = 0.035), those who frequently skipped meals (p < 0.001), those who do not have breakfast regularly (p = 0.002), those who spend more than four hours a day using a tablet/computer (p = 0.007), those who watch television more than 2 hours a day (p = 0.003), those who do not have regular sleep (p = 0.012), those who sleep less than 8t hours a night (p = 0.031), those who do not spend quality time with their families at least 2 days a week (p = 0.002) and those who do not have a hobby or sport that they were constantly interested in (p = 0.007).

Conclusion: The finding of the present study show that CPRS score in children is associated with some factors such as mother's habits in pregnancy, behaviours in having meals, daily habits and regular sleep. Although eating habits are a risk factor for ADHD, when the right eating habits are acquired, they can reduce the risk or symptoms of ADHD. However, more extensive and valid studies should be conducted to better explain this issue.
