Association of moderate and vigorous physical activity and relative muscle strength with neck circumference: a cross-sectional analysis of the Study of Health in Pomerode (SHIP-Brazil).

OBJECTIVE: Neck circumference is a simple anthropometric measurement that may be linked to chronic diseases, physical activity, and muscle strength. We sought to verify the association of moderate and vigorous physical activity levels and relative muscle strength with neck circumference in a community in southern Brazil. METHODS: We cross-sectionally analyzed data from 2,488 participants (51% women), aged 20-79 years old from the Study of Health in Pomerode (SHIP-Brazil) conducted in Pomerode, Santa Catarina, Brazil. Increased neck circumference was defined with cutoff points of >39cm for men and >35cm for women. The independent variables were the level of moderate and vigorous physical activity using the short International Physical Activity Questionnaire, and relative muscle strength using the handgrip test and body mass. Univariate and multiple Poisson regression models were used to determine the association between variables (p≤0.05). RESULTS: The prevalence of increased neck circumference was 48.2% (60.4% in men, 39.6% in women) and was associated with low relative muscle strength (PR=1.26, 95%CI: 1.17-1.35) in men, insufficient moderate and vigorous physical activity levels (PR=1.23, 95%CI: 1.14-1.32), and relative muscle strength (PR=1.73, 95%CI: 1.61-1.87) in women. After adjusting for covariates, no significant associations were observed between insufficient moderate and vigorous physical activity levels in men (PR=1.02, 95%CI: 0.95-1.07). CONCLUSION: Increased neck circumference seems to be an important predictor of low moderate and vigorous physical activity and relative strength loss in adults, and more pronounced in women.

ABSTRACT Objective Neck circumference is a simple anthropometric measurement that may be linked to chronic diseases, physical activity, and muscle strength. We sought to verify the association of moderate and vigorous physical activity levels and relative muscle strength with neck circumference in a community in southern Brazil.

Relação entre estilo de vida e desempenho acadêmico / Relationship between lifestyle and academic performance / Relación entre el estilo de vida y el rendimiento académico

Objetivo: Investigar a associação do estilo de vida com o desempenho acadêmico de estudantes de Educação Física. Métodos: Estudo transversal envolvendo 186 estudantes de Educação Física de uma universidade de Santa Catarina, Brasil. Realizou-se a coleta de dados, entre agosto e novembro de 2018, com o questionário "Estilo de Vida Fantástico", composto por 25 questões em nove domínios (família e amigos/ atividade física/ nutrição/ cigarro e drogas/ álcool/ sono, cinto de segurança, estresse e sexo seguro/ tipo de comportamento/ introspecção/ trabalho). Para comparação entre estilo de vida e o desempenho acadêmico, representado pela média semestral, utilizou-se a análise de variância e o coeficiente de correlação de Pearson. Resultados: Verificou-se a média de idade de 22,3 anos (±4,87). O estilo de vida dos estudantes se apresentou, de forma geral, bom (34,1%) e muito bom (48,6%), e associado de forma positiva fraca (r=0,232), mas significativa (p=0,003), com o desempenho acadêmico. As médias semestrais de desempenho acadêmico diferenciaram-se em relação à classificação do estilo de vida (p=0,012). Os domínios família e amigos, cigarros e drogas, e álcool obtiveram pontuação satisfatória para um estilo de vida saudável. Conclusão: O estilo de vida dos acadêmicos de Educação Física avaliados é bom/muito bom nos domínios estudados e associa-se ao desempenho acadêmico.

Objective: To investigate the association of lifestyle with the academic performance of Physical Education students. Methods: it is a cross-sectional study consisting of 186 Physical Education students from a university in Santa Catarina, Brazil. Data were collected between August and November 2018 with the "Fantastic Lifestyle" questionnaire, consisting of 25 questions in nine domains (family and friends / physical activity/nutrition/ smoking and drugs/alcohol/ sleep, safety belt, stress, and safe sex/behavior type/introspection/ work). We used the analysis of variance and Pearson's correlation coefficient to compare lifestyle and academic performance, represented by the semester average. Results: The mean age was 22.3 years (± 4.87). Students' lifestyles were generally good (34.1%) and very good (48.6%), and associated positively weak (r = 0.232) but significant (p = 0.003), with academic performance. Semiannual averages of academic performance differed to lifestyle classification (p = 0.012). The domains family and friends, cigarettes and drugs, and alcohol scored satisfactorily for a healthy lifestyle. Conclusion: The lifestyle of the evaluated Physical Education students is good / very good in the studied domains and is associated with academic performance.
