A recent alarming rise of neurodegenerative diseases in the developed world is one of the major medical issues affecting older adults. In this review, we provide information about the associations of physical activity (PA) with major age-related neurodegenerative diseases and syndromes, including Alzheimer’s disease, vascular dementia, and mild cognitive impairment. We also provide evidence of PA’s role in reducing the risks of these diseases and helping to improve cognitive outcomes in older adults. Finally, we describe some potential mechanisms by which this protective effect occurs, providing guidelines for future research.
Among early adolescents (10–14 years), poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA) children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one of the primary contributors to obesity is important. Early adolescents consume foods and beverages during eating occasions that occur with and without parental supervision. Parents may influence eating behaviors of early adolescents during eating occasions when they are present or during independent eating occasions by engaging in practices that affect availability of foods and beverages, and through perceived normative beliefs and expectations for intake. Therefore, the purpose of this article was to describe the influence of parenting practices on eating behaviors in general and when specifically applied to independent eating occasions of early adolescents. This information may be helpful to inform parenting interventions targeting obesity prevention among early adolescents focusing on independent eating occasions.
BackgroundLittle is known about preschool parents’ cognitions, barriers, supports and modeling of key obesogenic behaviors, including breakfast, fruit and vegetable consumption, sugary beverage intake, feeding practices, portion sizes, active playtime, reduced screen-time, sleep and selection of child-care centers with characteristics that promote healthy behaviors.MethodsThus, the purpose of this study was to examine these factors via survey and focus groups among 139 parents of 2- to 5-year-old children. Standard content analysis procedures were used to identify trends and themes in the focus group data, and Analysis of Variance was used to test for differences between groups in the survey data.ResultsResults showed 80% of parents ate breakfast daily, consumed sugary beverages 2.7 ± 2.5SD days per week, and had at least two different vegetables and fruits an average of 5.2 ± 1.8SD and 4.6 ± 2.0SD days per week. Older parents and those with greater education drank significantly fewer sugary drinks. Parents played actively a mean 4.2 ± 2.2 hours/week with their preschoolers, who watched television a mean 2.4 ± 1.7 hours/day. Many parents reported having a bedtime routine for their preschooler and choosing childcare centers that replaced screen-time with active play and nutrition education. Common barriers to choosing healthful behaviors included lack of time; neighborhood safety; limited knowledge of portion size, cooking methods, and ways to prepare healthy foods or play active indoor games; the perceived cost of healthy options, and family members who were picky eaters. Supports for performing healthful behaviors included planning ahead, introducing new foods and behaviors often and in tandem with existing preferred foods and behaviors, and learning strategies from other parents.ConclusionsFuture education programs with preschool parents should emphasize supports and encourage parents to share helpful strategies with each other.
The L.E.A.D. (Locate, Evaluate, and Assemble Evidence to Inform Decisions) framework of the Institute of Medicine guided the assembly of transdisciplinary evidence for this comprehensive, updated review of family meal research, conducted with the goal of informing continued work in this area. More frequent family meals are associated with greater consumption of healthy foods in children, adolescents, and adults. Adolescents and children who consume fewer family meals consume more unhealthy food. School-aged children and adolescents who consume more family meals have greater intakes of typically underconsumed nutrients. Increased family meal frequency may decrease risk of overweight or obesity in children and adolescents. Frequent family meals also may protect against eating disorders and negative health behaviors in adolescents and young adults. Psychosocial benefits include improved perceptions of family relationships. However, the benefits of having a family meal can be undermined if the family consumes fast food, watches television at the meal, or has a more chaotic atmosphere. Although these findings are intriguing, inconsistent research methodology and instrumentation and limited use of validation studies make comparisons between studies difficult. Future research should use consistent methodology, examine these associations across a wide range of ages, clarify the effects of the mealtime environment and feeding styles, and develop strategies to help families promote healthful mealtime habits.
Bodybuilding has increasingly become popular between males since male body shape has become a subject of interest in the last decades. Bodybuilders have desired to gain more muscle and paid attention to their body shape. Based on this purpose, they have string rules that include restrictive eating and excessive exercise program. Recent research has demonstrated that desiring more muscular body shape exhibits eating behavior problems and body dissatisfaction issues in bodybuilders. Limited research exists on the relationship between body dissatisfaction and eating disorders in male bodybuilders. The aim of this study was to determine the relationship between body image disturbance and eating disorders in 120 male bodybuilders. The Eating Attitude Test (EAT-40) was used to determine eating disorders, the Muscle Dysmorphia Disorder Inventory was used to determine bigorexia symptoms, and Bodybuilder Image Grid-Original (BIG O) and Scaled (BIG S) forms were used to detect the factors associated with body dissatisfaction. There was a positive relationship between Eating Attitude Test and Muscle Dysmorphia Disorder Inventory total scores. Eating Attitude Test was positively correlated with both fat and muscle dissatisfaction. Our results indicated that eating disorder psychopathology is positively related to body dissatisfaction and body dysmorphic disorders in male bodybuilders.
