When Do Individuals Get More Injured? Relationship between Physical Activity Intensity, Duration, Participation Mode, and Injury

The present study examines the association between physical activity (PA) participation modes (i.e., family, friends, club members, and alone), PA volumes (i.e., intensity and duration), gender, and injury. A total of 9000 Koreans aged 10–89 years participated in the Korean Survey of Citizens’ Sports Participation project. However, participants who did not respond to a question regarding PA participation modes (n = 2429) and those under 18 years old (n = 489) were excluded from this study. Analysis of variance (ANOVA) was used to compare the groups’ characteristics and the association between PA participation modes and injury was demonstrated by conducting multinomial logistic regression analysis. The risk of injury was significantly higher in the friend and club member groups than in the alone group. In addition, PA intensity and gender were critical risk factors of injury, while PA duration showed no significant results. The results indicated a strong association between PA participation modes, PA intensity, gender, and injury, and an interesting finding is that more injuries derived from a higher intensity of PA, not from a longer duration of PA. Therefore, this present study directly documented that considerable attention should be placed on the factors that affect injuries, such as gender and PA intensity, to prevent unpredictable injury and encourage potential participants to exercise with diverse participation modes and appropriate intensity.

Dietary diversity practice and associated factors among late adolescent girls in Tegede district high Schools, northwest Ethiopia

Introduction: Estimating the dietary and nutrient intake is one of the indirect methods of assessing nutritional status. Diets of adolescent girls in developing countries including Ethiopia are low in diversity, mostly consuming cereals with limited animal source foods and essential nutrients that led to malnutrition. The problem is highly exacerbated at adolescent stage, which exhibited rapid physiological changes. Hence, this study aimed to assess dietary diversity and associated factors among high school late adolescent girls in Tegede district.Methods: A school based cross-sectional study was conducted on 400 systematically selected adolescent girls from January to February 2018 in Tegede district high schools. Dietary diversity score was measured using a validated 24-hour dietary recall questionnaire based on 10 food groups. Binary logistic regression was used and Bi-variable and multivariable analysis were used to identify factors associated with dietary diversity and 95% confidence interval and Odds Ratio (OR) was computed to assess the strength of association. Variables with 0.05 p-value in the multivariable analysis were taken as significantly associated with the dietary diversity score.Result: The proportion of adolescent girls who had adequate dietary diversity was 47.3% [95% CI: (42- 52%)]. Urban residences [AOR=6.60(3.90 11.16)], Living with family [AOR=5.53(3.26 9.37], common decision on food preparation at household level [AOR=1.97(1.14 3.39], school nutrition club member [AOR=2.33(1.34 4.05)] and access to home gardening (AOR=2.69[(1.57 4.62)] were significant determinants of adequate dietary diversity.Conclusion: This study indicated the proportion of adolescent girls who had diversified diet was low. Family residences, Students living status, decision in home food preparation, school nutrition club member and access to home gardening were significant associated factors. These finding underscored that strengthening of school nutritional club and home gardening is mandatory to curb nutritional related problems.

Contrasting ideologies of foreign language learning in Japan: Hippo Family Club versus “traditional” education

This paper is based on ethnographic field work carried out between 2005 and 2009 in Japan with a language learning group called Hippo Family Club. Club member-learners attempt to acquire multiple languages at the same time through pseudo-natural immersion which treats language as play. As a result of this approach, members tend to develop novice-level abilities in a large number of languages.
