Influence of Adiposity on Physical Activity in Schoolchildren: The Moderator Role of Adherence to the Mediterranean Diet

Background: Studies were performed in order to determine the existing relationship between body composition and both physical activity (PA) levels and food habits. Nevertheless, no study has yet examined if the association between adiposity and PA in children is moderated by adherence to the Mediterranean diet (MD). Methods: the cross-sectional and associative analysis involved a total of 370 children (55.1% boys) aged 6–13, from six different schools from the Murcia region of Spain. Results: The different values of moderator [adherence to the MD expressed as a Mediterranean Diet Quality Index (KIDMED) score] are shown by the slope and the different areas of significance. The first area was shown below ≤3.8, indicating that the unfavorable influence of excess of adiposity on PA could be intensified for children in this area. The second area was a significant positive area was shown above ≥9.3, expressing that the unfavorable influence of adiposity could be reduced for those who were above this estimation point. Conclusion: Our findings reveal that the adverse effects of excess adiposity on PA can be moderated by adherence to the MD among schoolchildren.

Hypertensive Measures In Schoolchildren: Risk Of Central Obesity And Protective Effect Of Moderate-To-Vigorous Physical Activity.

ResumoFundamento Aumento da prevalência de hipertensão arterial (HA) em crianças e adolescentes e sua associação com diversas comorbidades.Objetivo Verificar a associação de HA, obesidade central e obesidade geral, e nível de atividade física em escolares.Métodos Participaram do estudo 336 crianças e adolescentes, de 11 a 17 anos de idade. Aferiram-se estatura, peso corporal, circunferência da cintura (CC) e pressão arterial (PA). Foi calculado o índice de massa corporal escore z (IMC-z). O nível de atividade física foi avaliado pela versão curta do International Physical Activity Questionnaire (IPAQ), conforme a prática em atividades físicas moderadas-vigorosas (AF-mv). Consideraram-se hipertensos os escolares que apresentaram pressão arterial sistólica (PAS) e/ou diastólica (PAD) superiores ao percentil 95, de acordo com sexo, faixa etária e estatura, ou ≥120×80mmHg. Utilizaram-se os testes estatísticos de t-Student , Qui-quadrado, Mann-Whitney e modelo de regressão logistica binária, considerando-se o nível de significância de p<0,05.Resultados Foram observados que 40,5% dos escolares apresentaram HA, 35,11% excesso de peso (12,5% obesos), 13,39% CC elevada e 40,2% foram considerados insuficientemente ativos em AF-mv. As chances de HA foram relacionadas à CC elevada (OR=6,11; IC95%:2,59 a 14,42) e ao excesso de peso (OR=2,91; IC95%:1,76 a 4,79). Além disso, os adolescentes que praticavam AF-mv apresentaram menor risco de PAD elevada (OR=0,33; IC95%:0,15 a 0,72).Conclusão Concluiu-se que a obesidade central, a obesidade geral e o sexo masculino foram os melhores preditores de HA em crianças e adolescentes. A prática de AF-mv demonstrou efeito protetor na PAD elevada em escolares. (Arq Bras Cardiol. 2020; 115(1):42-49)

Physical activity of school children and youth

Physical activity is a key element of a healthy lifestyle, especially in relation to children and adolescents. It is crucial for proper physical, psychological and social development. Systematic physical activity tailored to individual needs stimulates development in childhood and adolescence and increases health resources. Background: ‪PAn insufficient level of physical activity among children and adolescents, in comparison to the needs, is a problem occurring more and more commonly on a global scale. It has been confirmed in numerous research studies.

Influence of the Parental Educational Level on Physical Activity in Schoolchildren

The factors influencing physical activity participation in children are varied, although there is evidence that the educational level of parents may be one important factor. The aim of this study is to analyze the influence of parental education on the level of physical activity and the sedentary behavior of their children. The parents of 727 students, separated based on school group (preschool: n = 179; primary: n = 284; secondary: n = 230; high: n = 34), were invited to complete a series of questionnaires assessing their educational level (low, intermediate, and high) and their child’s level of physical activity and sedentary behavior. Primary school students with high- and intermediate-educated parents were found to engage in significantly more physical activity per week and spent more time engaged in homework than children with lower-educated parents. Secondary school students with higher-educated parents were found to spend significantly less time engaged in sedentary behavior than children with lower- or intermediate-educated parents, and high schoolers with higher-educated parents engaged in less tablet time than children with lower-educated parents. Multiple linear regression demonstrated that greater physical activity was precipitated by certain sedentary behaviors in children with more educated parents, such as total time watching TV (primary school), doing homework (secondary school), and total time using a tablet/similar (high school), which increased total time engaged in physical activity. These findings suggest that more educated parents may implement structured time for their children to engage in a balance of physical activity and sedentary behaviors.

Physical activity and individual accidental risk of infringement of the health of schoolchildren

Introduction. The optimal physical activity of schoolchildren ensures adequate physical development, considered as the totality of the morphological and functional properties of the body that characterize the process of its growth and maturation at each age interval. Main objective of research. To determine the values of individual accumulative risks of impairment of schoolchildren’s health components depending on the level of the physical activity and develop recommendations for their reduction. Material and methods. The study involved 709 schoolchildren aged 12-14 years. To solve the tasks there were used hygienic methods with an assessment of the physical mode, training mode, indicators of the functional capabilities of schoolchildren; anthropometric methods; information and analytical methods and statistical methods, including associative analysis. The level of physical activity of schoolchildren was classified according to daily energy expenditure, determined by summing energy expenditure across all categories of physical activity. Result and discussion. Individual accumulative risks of schoolchildren’s health problems were shown to be elevated in all components of health with an increase in the deviation of the level of physical activity from the optimum, and the time factor has a significant effect on the growth of individual accumulative risks of schoolchildren’s health problems. In order to reduce the likelihood of the formation of health disorders in schoolchildren, it has been established that the identification of physical activity impairments and the application of corrective measures should be carried out as early as possible - in the period up to 6 months from the moment when violations were detected. In drawing up a plan of corrective measures for the formation of an optimal level of average daily workload for school-age children, the categories of physical activity outside the normal range require a reduction to the recommended intensity and duration according to the gender and age. Associative rules have been obtained that allow identifying the causes of the disturbance of the structure of physical activity and make adjustments taking into account the relationship between categories of physical activity. The optimization was achieved by reducing the duration of time spent on various categories of physical activity to the recommended one. Conclusion. Application of the results of this study will reduce individual accumulative risks of violations of schoolchildren’s health, preserve the health of the younger generation, and provide optimal personal and physical development.

Factores asociados a riesgo cardiovascular en estudiantes de bachillerato de un colegio público de la ciudad de Santiago de Cali, Colombia

Introducción: las enfermedades cardiovasculares son la principal causa de muerte en todo el mundo, lo que las convierte en un problema de interés en salud pública, tanto para países desarrollados, como en vías de desarrollo. La disminución del tiempo dedicado a la actividad física y el aumento de las actividades sedentarias son parte de los muchos factores de riesgo para las enfermedades cardiovasculares. El objetivo fue determinar los factores asociados al riesgo cardiovascular en los estudiantes de una institución educativa de la ciudad de Cali, Colombia. Materiales y métodos: estudio epidemiológico observacional y analítico, con una muestra de 227 estudiantes seleccionados de forma aleatoria, con una confiabilidad del 95%. Para determinar el nivel de actividad física en los escolares, se aplicó el cuestionario internacional de actividad física IPAQ; igualmente, se tomaron medidas antropométricas como peso, talla, perímetro de cintura y cadera. Resultados: el 96% de los participantes presentó riesgo cardiovascular bajo. Así mismo, las variables que mostraron una asociación estadísticamente significativa con el riesgo cardiovascular fueron el consumo de alcohol y el índice de masa corporal, los cuales predicen en un 81 % la posibilidad de tener riesgo. Conclusiones: prevaleció el bajo riesgo cardiovascular y el alto nivel de actividad física en los escolares evaluados, con diferencias significativas respecto al sexo. Los hombres presentan valores más altos en peso, talla y relación cintura/cadera en comparación con las mujeres. Se estableció que los factores asociados con el riesgo cardiovascular son el índice de masa corporal y el consumo de alcohol.

Effect of the day and the number of days of application on reproducibility of a questionnaire to assess the food intake in schoolchildren.

The Food Intake and Physical Activity of School Children (Web-CAAFE) is an online questionnaire developed to monitor the diet and physical activity of Brazilian schoolchildren. The study aimed to evaluate the effect of the day of the week and the number of applications on Web-CAAFE reproducibility. Schoolchildren in grades 2 to 5 of two municipal schools in Florianópolis (n = 197) filled out the Web-CAAFE twice in the same day, of which 113 filled out the instrument in three non-consecutive days. The analysis was performed using the intraclass correlation (ICC) and logistic regression was used to evaluate the factors associated with poor reproducibility. The reproducibility of the questionnaire was significantly lower for children who filled out their consumption mostly on weekends in relation to weekdays (OR = 2.93; p = 0.045), and was significantly better in girls in relation to boys (OR = 0.29; p< 0.001). Higher CCI was observed on the second and third day of Web-CAAFE application in relation to the first day. These results are relevant for planning future studies that use dietary assessment instruments in children, especially on evaluation of their validity and reproducibility. The results suggest that at least two days provides acceptable reproducibility results of the Web-CAAFE and that the weekend recall may reduce the reproducibility.

Association between level and domains of physical activity in schoolchildren from 9 to 12 years

To analyze the relationship between the level and domains of physical activity in school children from 9 to 12 years of public educational institutions of the Municipality of Los Patios, Cucuta, 2017, based on the information obtained through the questionnaire PAQ-C (Physical Activity Questionnaire for children). Descriptive, transversal and analytical study. With a sample of 777 schoolchildren, a proportional stratified sampling was carried out. Consent and informed consent were signed, then the PAQ-C questionnaire was applied. 50,3% of schoolchildren are girls; 44% present a moderately active level, the free time domain has a greater degree of association with a correlation coefficient of 0,65 and is significant at a level of 0,01, followed by the household domain with a correlation coefficient of 0,617 and the school role 0,502. It was determined that the level of physical activity of school children is moderately active and that it decreases with age, we can say that boys are more active than girls, in addition, there is a direct correlation between the domains and the general level of activity physical.

The effect of a curriculum-based physical activity intervention on accelerometer-assessed physical activity in schoolchildren: A non-randomised mixed methods controlled before-and-after study.

Classroom-based physical activity (PA) interventions offer the opportunity to increase PA without disrupting the curriculum. We aimed to explore the feasibility and potential effectiveness of a classroom-based intervention on moderate to vigorous PA (MVPA) and total PA. The secondary aim was to assess the acceptability and sustainability of the intervention. In a mixed-methods, non-randomised, exploratory controlled before-and-after study, 152 children (10 ± 0.7 years) were recruited from five schools; two intervention (n = 72) and three control (n = 80) schools. School teachers delivered an 8-week classroom-based intervention, comprising of 10 minutes daily MVPA integrated into the curriculum. The control schools maintained their usual school routine. Mean daily MVPA (min), total PA (mean cpm), physical fitness, and health-related quality of life measurements were taken at baseline, end of intervention, and 4-weeks post-intervention (follow-up). Data were analysed using a constrained baseline longitudinal analysis model accounting for the hierarchical data structure. For the primary outcomes (MVPA and total PA) the posterior mean difference and 95% compatibility interval were derived using a semi-Bayesian approach with an explicit prior. The acceptability and sustainability of the intervention was explored via thematic content analysis of focus group discussions with teachers (n = 5) and children (n = 50). The difference in mean daily MVPA (intervention-control) was 2.8 (-12.5 to 18.0) min/day at 8 weeks and 7.0 (-8.8 to 22.8) min/day at follow-up. For total PA, the differences were -2 (-127 to 124) cpm at 8-weeks and 11 (-121 to 143) cpm at follow-up. The interval estimates indicate that meaningful mean effects (both positive and negative) as well as trivial effects are reasonably compatible with the data and design. The intervention was received positively with continuation reported by the teachers and children. Classroom-based PA could hold promise for increasing average daily MVPA, but a large cluster randomised controlled trial is required.

Association of Teacher-Level Factors With Implementation of Classroom-Based Physical Activity Breaks.

Classroom-based physical activity (CBPA) breaks are a common strategy to increase elementary school children's physical activity (PA) levels. There is limited research examining how teacher-level factors impact teacher implementation of CBPA breaks. In this study, we assessed the relationship of teacher-level factors with teacher use of a CBPA resource. We randomized 6 elementary schools in rural Oregon into control (N = 3) or intervention (N = 3) conditions. Each teacher at intervention schools received the CBPA resource. Teachers at control schools received 1 CBPA-Toolkit per grade level to share, and received no training. We surveyed teachers on their use of the toolkit, implementation support and self-efficacy, and value for PA. Logistic regression was used to examine the odds of toolkit use by teacher-level factors. Among survey respondents (N = 83), 57% were self-identified toolkit users and 48% attended a training. Training participation and teacher implementation self-efficacy were associated with greater odds of using the toolkit (odds ratio, OR = 7.76 [95% confidence interval, CI = 1.39-43.19] and OR = 5.54 [95% CI = 1.24-23.87], respectively). CBPA tools supported with training aimed at developing teachers' implementation self-efficacy increased the likelihood of teachers employing CBPA tools.

Sports Contribute to Total Moderate to Vigorous Physical Activity in School Children.

ABSTRACTIntroductionA third of all children spend at least 60 min·d−1 in moderate to vigorous physical activity (MVPA) as recommended by the World Health Organization. We investigated the distribution of objectively measured physical activity (PA) intensities achieved by schoolchildren during physical education (PE) and organized youth sports (OYS) and the contribution of PE and OYS to the achievement of the PA recommendations.MethodsIn two surveys, PA of 396 children was measured using accelerometry during typical school weeks. Proportions (%) of sedentary behavior, light PA, and MVPA per day and particularly during sports were assessed in children 6–17 yr old. Adjusted odds ratios (AOR) were calculated to analyze the association between frequency (d·wk−1) and duration (min·wk−1) of PE and OYS and meeting the PA recommendations.ResultsAverage proportions of MVPA during PE and OYS ranged between 15% and 31%. Between 68% and 74% of children (6–10 yr) and between 27% and 37% of adolescents (11–17 yr) met the PA recommendations. In both age-groups, PE and OYS on at least 2 d·wk−1 were both significantly associated with meeting the PA recommendations (AOR for PE = 3.60, 95% confidence interval [CI] = 2.05–6.31; AOR for OYS = 3.83, 95% CI = 2.09–6.99), compared with no PE or no OYS in that week. Likewise, significant AOR values were found for >90 min of PE per week (AOR = 3.48, 95% CI = 2.03–5.98) and >120 min of OYS per week (AOR = 3.72, 95% CI = 2.01–6.89), compared with no PE or no OYS in that week, respectively.ConclusionSchoolchildren spent less than one-third of PE and OYS in MVPA. PE and OYS were found to support children and adolescents to engage sufficiently in MVPA as recommended by the World Health Organization.

Dietary habits, energy drink consumption, obesity, and physical activity in marginalised Palestinian schools in the West Bank: a cross-sectional study

BackgroundSocioeconomic factors have been found to be related to adolescents' dietary habits, physical activity, and body mass index (BMI). 50 schools in the West Bank that face socioeconomic and political challenges in terms of infrastructure, academic achievement, dropout rate, limited access, geography, and economic status were labelled as marginalised by the AMIDEAST School Support Program (SPP). This study aimed to describe and assess factors relating to dietary habits, energy drink consumption, BMI index, and physical activity in Palestinian adolescents attending marginalised schools. MethodsMarginalised schools (n=50) were stratified by district and gender to select a random sample of 20 schools. All students in sixth or ninth grades in the targeted schools were interviewed one-to-one by one of 14 senior dental students who were trained and calibrated by a public health specialist. The schoolchildren were asked about their dietary habits, such as daily consumption of added sugar, carbonated drinks, sweetened juices, and energy drinks. Daily intake of milk, fruits, vegetables, nuts, and non-vegetarian food were also assessed. In addition, schoolchildren's physical activity, father's employment and mother's education were recorded. Weight and height were measured, and BMI percentile was calculated. Parental informed consents were collected by the school administration. Ethics approval for the study was obtained from Al-Quds University Scientific Research Ethics Committee. FindingsA total of 1282 students out of 1308 completed the questionnaire; a response rate of 98%. Of our sample, 6% (77 of 1282) were underweight (5th percentile or under) and 34% (436 of 1282) were overweight or obese (85th percentile or over). Among sixth graders, 43% (155 of 360) of the boys and 24% (59 of 247) of the girls were overweight or obese. The opposite was true for ninth graders; 20% (54 of 268) of the boys and 42% (158 of 377) of the girls were overweight or obese. Ninth graders had more added sugar in their diet than sixth graders (p=0·002), less milk consumption (p<0·0001), more energy drink consumption (p=0·001), and less physical activity (p<0·0001). Consumption of carbonated and sweetened drinks was associated with being overweight or obese (p=0·016, p=0·001). Consumption of carbonated drinks was higher among children of mothers with a high-school education than among children of mothers with college degrees (p<0·0001). In addition, children of mothers educated to high school level or below were associated with being underweight (p=0·05) InterpretationThe results of this study suggest that dietary habits worsen between the ages of 12 years and 15 years. The mother's level of education is an important factor in being overweight or underweight. Interventions to increase awareness of the importance of healthy diets and physical activity among adolescents and their mothers should start before the age of 12 years.

Stay in or play out? The influence of weather conditions on physical activity of grade 5 children in Canada.

Regular physical activity (PA) in children is essential for their development and prevention of overweight and obesity. Little is known about the effect of day-to-day variations in weather conditions on PA levels in school-aged children, particularly with regard to school compared to non-school days and girls compared to boys. Daily step count (7:00 a.m.-9:00 p.m.) from 972 grade 5 students aged 10-11years from 60 schools across Alberta, Canada, was collected using time-stamped pedometers (minimum wear time of two school and one non-school days) during March-June 2013. Time-matched weather conditions (actual and feels-like temperature, cloud coverage, and precipitation amount) were obtained from local weather stations in Alberta during the same period. Multilevel mixed-effect regression models were used to estimate the effect of each weather condition on daily step count. A 1°C increase in feels-like temperature was associated with 26 more steps/day (p < 0.05), while 1-unit increase in cloud coverage was associated with 61 fewer steps/day (p < 0.01). Compared to no precipitation, heavy precipitation (> 5mm/day) was associated with 1022 fewer steps/day (p < 0.01). Students' PA levels were associated with weather conditions more on non-school vs. school days and more among girls vs. boys. Results suggest that daily weather conditions can affect PA in school children, particularly outside school hours, and should be considered when evaluating PA levels or designing interventions to promote PA in children. Findings provide support for increased investment toward creating weather-appropriate physical activity opportunities for wet and colder days to prevent PA decline in children during inclement weather conditions.

Web-based intervention to promote physical activity in Taiwanese children

PurposeThis study investigated the effectiveness of a theory-based, technology-integrated website in promoting the physical activity of schoolchildren. Design and methodsA website designed using a self-management strategy and supplemented with a geographical information system (GIS) mapping function was used to increase children's physical activity levels. A total of 524 students from six elementary schools in Taipei City completed surveys at three times during 2010 and were assigned to one of three groups: (1) a self-management group, using a website employing a goal-setting strategy and a storytelling schema based on a classical Chinese novel; (2) a knowledge-only group that was given only access to the website; or (3) a control group that was only given lectures and not allowed to access the website. ResultsAfter adjustment for the effects of the pretest, the self-management and knowledge-only groups were found to be more physically active and have higher self-efficacy than the control group. Moreover, the self-management group had higher scores for these two variables than the knowledge-only group. Furthermore, the intervention was more effectives for male students than female students. ConclusionOverall, the self-management website proved to be effective in promoting schoolchildren's physical activity. The positive correlation of self-efficacy with the ability to handle the difficulties inherent in physical activity continued for 3 months after the intervention was completed.

Empirically derived dietary patterns through latent profile analysis among Brazilian children and adolescents from Southern Brazil, 2013-2015.

The aims of this study were to identify dietary patterns (DPs) of children and adolescents participating in three cross-sectional surveys (2013–2015) and to test their associations with sociodemographic variables, physical activity (PAS), screen-based sedentary activity (SA), and weight status. One-day data were obtained from 5,364 schoolchildren (7–12 years) from public schools of Florianopolis (South of Brazil), using the validated questionnaire Web-CAAFE (Food Intake and Physical Activity of Schoolchildren). DPs were derived from the frequency of daily consumption of 32 foods/beverages by latent profile analysis. Multinomial logistic regression analysis was used to estimate the association of the DPs with sociodemographic variables, physical activity, screen activity and weight status. ‘Traditional’, ‘Monotonous’, and ‘Mixed’ DPs were identified. The percentages of children and adolescents within these profiles were 41.3, 36.3, and 22.4%, respectively. Children and adolescents in the highest tertiles of both PAS and daily frequency of SA had a higher probability to present a ‘Mixed’ DP compared to peers with less PAS and SA. Children and adolescents who reported having a school meal were significantly more likely to present the ‘Traditional’DP, while boys who did not report having a school meal had a higher probability to present the ‘Monotonous’ DP. The DPs were not associated with the year of survey, age, family income, or weight status.

EFFECTIVENESS OF OBESITY INTERVENTION PROGRAMS BASED ON GUIDELINES FOR ADOLESCENT STUDENTS: SYSTEMATIC REVIEW.

ABSTRACTObjective: To verify the effectiveness of educational interventions based on guidance on physical activity and nutrition in schoolchildren. Data sources: A systematic search was carried out in four electronic databases containing articles published between October 2007 and January 2017 and addressing educational interventions with emphasis on both nutritional education and physical activity in schoolchildren and adolescents aged 10 to 19 years. Data synthesis: Twelve articles were selected for this review, of which four included only educational interventions; four made and association between educational interventions, inclusion of healthy foods and physical activity; two made a relation between guidelines and physical activity; and finally, two associated guidelines with consumption of healthy foods. Conclusions: Interventions based on physical activity and/or nutrition counseling were efficient and showed superior results in studies that associated the practice of physical activity with counseling. However, the need for new studies on educational interventions among schoolchildren and adolescents was made evident.

Mediterranean diet, weight status and physical activity in schoolchildren of the Region of Murcia

IntroductionChildhood and adolescence are key stages to promote a healthy lifestyle. ObjectiveTo analyse the relationship between weight status, physical activity and the Mediterranean diet in schoolchildren in the Region of Murcia. MethodsCross-sectional descriptive study with 520 schoolchildren aged 8–17 years. The weight status was calculated through the body mass index. The Mediterranean diet was found through the KIDMED questionnaire and physical activity was estimated using the IPAQ-C and IPAQ-A questionnaires. ResultsThe Mediterranean diet is not significantly associated with sex (p<0.537) or weight status (p<0.417) but it maintains a relationship of dependence with age (p<0.010) and the level of physical activity (p<0.000). Schoolchildren in normal weight and assets have a greater follow-up to the Mediterranean diet than their overweight and sedentary peers (p<0.000). ConclusionThe fat but fit phenomenon applied to the Mediterranean diet is confirmed.

Nível de atividade física e apoio social dos pais e amigos em escolares da rede pública

&#x0D; &#x0D; &#x0D; O estudo teve como objetivo analisar a associação entre apoio social e nível de atividade física em escolares. Pesquisa com delineamento transversal, caracterizou-se como censo escolar, visto que en- volveu toda população escolar do Ensino Fundamental II e Médio, de 10 a 18 anos de idade, de oito escolas públicas existentes na cidade de Paranavaí, Paraná (n= 2.759, 14, 3 ± 3,3 anos, 50,5% meninas e 49,5% meninos. O nível de atividade física foi analisado por uma adaptação do questionário Self Administered Physical Activity Checklist, e o ponto de corte para inadequação do nível de atividade física foi &lt;300 minutos por semana. O apoio social de pais e amigos para a prática de atividade física foi avaliado por meio da escala de Apoio Social para Atividade Física em Adolescentes (ASAFA), sendo considerado como inadequado quando das respostas foram nunca e raramente. As análises estatísticas foram feitas por meio do Statistical Package for a Social Science (SPSS), versão 20.0, considerando-se um nível de significância de 5%. Os resultados mostraram que escolares com apoio social inadequado dos pais, dos amigos ou de ambos, possuíam, respectivamente, 2,0 (IC95%: 1,6-2,6), 1,5 (IC95%: 1,2-2,9) e 1,6 (IC95%: 1,2-2,1) mais de chances de serem insuficientes ativos em relação aos que tinham o apoio social adequado. Existe associação entre nível de atividade física e apoio social de pais e amigos em escolares da rede pública de ensino. Nesse sentido, sugere-se às escolas que sejam desenvolvidas iniciativas para conscientização de pais e amigos quanto a sua importância com vistas à adoção da prática de atividade física em adolescentes.&#x0D; &#x0D; &#x0D;
