Changes in Weight, Sedentary Behaviour and Physical Activity during the School Year and Summer Vacation.
International journal of environmental research and public health, 2018Co-Authors: Chiaki Tanaka, John J. Reilly, Maki Tanaka, Shigeho TanakaAbstract:Background: To examine bidirectional associations between body weight and objectively assessed sedentary behaviour (SB) and physical activity (PA) during the school year and Summer Vacation. Methods: Participants were 209 Japanese boys and girls (9.0 ± 1.8 years at baseline). SB and PA were measured using triaxial accelerometry that discriminated between ambulatory and non-ambulatory PA, screen time measured by questionnaire during the school-term was evaluated in May and the Summer Vacation, and relative body weight measured in May and just after the end of Summer Vacation. Results: There were no significant relationships between changes in SB or PA and changes in body weight. However, higher relative body weight at baseline was associated with decreased non-ambulatory moderate PA (p = 0.049), but this association was slightly diminished after adjusting for change in SB (p = 0.056). Longer screen time at baseline was also associated with increased relative body weight (p = 0.033). Conclusions: The present study revealed that body weight might be particularly influential on non-ambulatory moderate PA while SB, PA or changes in these variables did not predict changes in body weight. Moreover, screen time during the school year is a predictor of change in relative body weight during the subsequent Summer Vacation.

Seasonal changes in objectively measured sedentary behavior and physical activity in Japanese primary school children.
BMC public health, 2016Co-Authors: Chiaki Tanaka, John J. Reilly, Maki Tanaka, Shigeho TanakaAbstract:The recent prevalence of obesity in Japanese children is much higher compared to 1980. The present study compared daily sedentary behavior (SB) and physical activity (PA) between the school year and Summer Vacation in Japanese primary school children. Participants were 98 Japanese boys (8.9 ± 1.8 years at baseline) and 111 girls (9.1 ± 1.8 years). SB and PA were measured in May (school term) and July/August (Summer Vacation), 2011. SB and PA were assessed using a triaxial accelerometer (Active style Pro HJA-350IT, Omron Healthcare) for 7 consecutive days. The average number of minutes spent in SB (no more than 1.5 metabolic equivalents (METs)), light intensity activity (LPA; more than 1.5 to less than 3.0 METs) and moderate-to-vigorous physical activity (MVPA; 3.0 METs or more), and step counts were calculated for each individual. Moreover, the determinants/moderators of changes in SB and PA were examined. Daily SB was significantly higher in the Summer Vacation than in the school year for both boys and girls (p

Children's development of semantic verbal fluency during Summer Vacation versus during formal schooling
'Informa UK Limited', 2020Co-Authors: Rosqvist Ida, Sandgren Olof, Andersson Ketty, Hansson Kristina, Lyberg-Åhlander Viveka, Sahlén BirgittaAbstract:Children's results on school-related achievements tests, such as aspects of math, reading and writing, have been shown to decline following a lengthy Summer Vacation. Few studies have investigated whether this also applies to vocabulary skills. The purpose of this study is to investigate how lexical organization and retrieval, assessed by a semantic verbal fluency (SVF) task, develops during a lengthy Summer Vacation versus formal schooling. Sixty-eight children with mean age of 7.9 (ranging from 6.5 to 9.1), were assessed pre- and post-Summer Vacation and post-fall semester using two SVF categories (Animals and Clothes). The number of words produced in both categories gave the total score. The result of the SVF tests decreased following Summer Vacation. The loss was recouped at the post-fall semester assessment, but no gains compared to initial testing were shown. Neither level of parental education, general language ability, non-verbal IQ, nor bilingualism explained the variance in development during the Summer Vacation or the fall semester. Our findings indicate that a lengthy Summer Vacation causes a recess in the expected development of SVF ability and that this recess is recouped after a semester of formal schooling. The findings are in line with previous research indicating that Summer Vacation may have negative impact on the development of important scholastic abilities in children

Development of semantic verbal fluency and narrative ability during Summer Vacation versus formal schooling
2019Co-Authors: Rosqvist Ida, Sandgren Olof, Andersson Ketty, Hansson Kristina, Lyberg-Åhlander Viveka, Sahlén BirgittaAbstract:The detrimental effect of a lengthy Summer Vacation on important scholastic abilities such as reading, writing and mathematical skills is relatively well documented, but how language skills are affected by Summer Vacation is less investigated. The purpose of our study is to investigate how lexical organization and retrieval assessed by a semantic verbal fluency (SVF) task and oral narrative ability develops during Summer Vacation compared to during formal schooling, and if the development differs between monolingual and bilingual children. The participants (n = 68, MAgeT1 = 7;9) were assessed with a semantic verbal fluency (SVF) task with two categories (Animals and Clothes). A subsample (n = 20, MAgeT1 = 7;11) was evenly divided into two groups, monolingual and bilingual, matched for age and sex. The Swedish narrative production of the participants was assessed with MAIN (Gagarina et al., 2012) and scored with Narrative Scoring Scheme (NSS) (Miller et al., 2003; Heilmann et al., 2010), adapted to MAIN in Swedish. Both the SVF and narrative task showed a similar pattern with a decrease in scores following the Summer Vacation and a positive development following formal schooling. For SVF the participants had significantly lower scores post-Summer Vacation than pre-Summer. However, the pre-Summer scores did not differ significantly from the post-fall semester scores, indicating that the participants needed the fall semester to recoup from the losses made over the Summer Vacation, but that no additional gains had been made. When comparing the narrative development during Summer Vacation and formal schooling a negative development during the Summer Vacation and a positive development during formal semester was observed, although not significant. No statistically significant differences were found when comparing development of SVF and narrative ability of the monolingual and bilingual group during neither Summer Vacation, nor formal schooling. However, a slightly higher NSS mean change during formal schooling was observed for the bilingual group. The results of this study validate previous findings of a negative effect of Summer Vacation on language measures. The results show a negative effect of Summer Vacation and positive effect of formal schooling on semantic verbal fluency and narrative ability (although ns). No statistically significant differences in development during neither Summer Vacation nor formal schooling is seen between monolingual and bilingual participants.REFERENCESGagarina, N., Klop, D., Kunnari, S., Tantele, K., Välimaa, T., Balciuniene, I., Walters, J.
