Consumo alimentar, estado nutricional e nível de atividade física em comunidade universitária brasileira

OBJECTIVE: This study assessed the food intake variability and frequency, nutritional status and level of physical activity of a university community in Brazil. METHODS: The sample comprised 303 volunteers (130 men and 173 women) from a university community in Sao Paulo state. They answered the International Physical Activity Questionnaire online and reported their weight and height. Statistical treatment included descriptive analysis, analysis of food intake frequency (Dietsys) and Spearmans rank correlation coefficient. RESULTS: Eating habits were inappropriate and many individuals were overweight or obese. There were more correlations among food groups for women who had better diets than men but the level of physical activity did not differ between the genders. There was no significant correlation between food groups and body mass index or level of physical activity for men or women. CONCLUSION: The study university community consumes little fruit, non-starchy vegetables, grains and legumes.

Application of exploratory factor analysis to assess fish consumption in a university community

The objective of this research was to use the technique of Exploratory Factor Analysis (EFA) for the adequacy of a tool for the assessment of fish consumption and the characteristics involved in this process. Data were collected during a campaign to encourage fish consumption in Brazil with the voluntarily participation of members of a university community. An assessment instrument consisting of multiple-choice questions and a five-point Likert scale was designed and used to measure the importance of certain attributes that influence the choice and consumption of fish. This study sample was composed of of 224 individuals, the majority were women (65.6%). With regard to the frequency of fish consumption, 37.67% of the volunteers interviewed said they consume the product two or three times a month, and 29.6% once a week. The Exploratory Factor Analysis (EFA) was used to group the variables; the extraction was made using the principal components and the rotation using the Quartimax method. The results show clusters in two main constructs, quality and consumption with Cronbach Alpha coefficients of 0.75 and 0.69, respectively, indicating good internal consistency.

Correlação entre nível de renda e os domínios da qualidade de vida de população universitária brasileira

OBJETIVO: O presente estudo teve por objetivo avaliar a associacao entre renda e os dominios da qualidade de vida de uma amostra da comunidade universitaria do Brasil. METODOS: A amostra constou de 1966 sujeitos da comunidade universitaria da Universidade Estadual de Sao Paulo (USP). A coleta de dados foi realizada por meio da internet . A avaliacao da qualidade de vida deu-se pela aplicacao do instrumento WHOQOL-bref (OMS), composto de 26 questoes, sendo 24 questoes distribuidas em 4 dominios - fisico, psicologico, relacoes sociais e meio ambiente - e duas questoes que avaliam a qualidade de vida geral. Para a classificacao do nivel de renda foi considerado a renda familiar em salarios minimos (SM) por niveis de ate 1 SM, entre 2 e 3 SM, entre 4 e 6 SM, entre 7 e 9 SM, e mais que 10 SM. Foi realizada a analise descritiva dos dados, teste de aderencia a distribuicao normal e, posteriormente, o teste de coeficiente de correlacao de Spearman foi aplicado para identificar possiveis associacoes entre renda e dominios da qualidade de vida. RESULTADOS: Os resultados de qualidade de vida indicaram maior valor medio no dominio fisico e menor valor medio no dominio meio ambiente. Ja os dados sobre a renda indicaram prevalencia de pessoas que recebem mais que 10 SM (40,5 %). O resultado indicou correlacao entre renda e o dominio meio ambiente. CONCLUSOES: O presente estudo permite concluir que o dominio do meio ambiente apresenta associacao com a renda, impactando a qualidade de vida da amostra estudada.
