Cross-cultural validity of the theory of planned behavior for predicting healthy food choice in secondary school students of Inner Mongolia.

AIMS: Unhealthy eating behavior is a serious health concern among secondary school students in Inner Mongolia. To predict their healthy food choices and devise methods of correcting unhealthy choices, we sought to confirm the cross-cultural validity of the theory of planned behavior among Inner Mongolian students. MATERIALS AND METHODS: A cross-sectional study, conducted between November and December 2014. Overall, 3047 students were enrolled. We devised a questionnaire based on the theory of planned behavior to measure its components (intentions, attitudes, subjective norms, and perceived behavioral control) in relation to healthy food choices; we also assessed their current engagement in healthy food choices. RESULTS: A principal component analysis revealed high contribution rates for the components (69.32%-88.77%). A confirmatory factor analysis indicated that the components of the questionnaire had adequate model fit (goodness of fit index=0.997, adjusted goodness of fit index=0.984, comparative fit index=0.998, and root mean square error of approximation=0.049). Notably, data from participants within the suburbs did not support the theory of planned behavior construction. Several paths did not predict the hypothesis variables. However, attitudes toward healthy food choices strongly predicted behavioral intention (path coefficients 0.49-0.77, p<0.01), regardless of demographic characteristics. CONCLUSION: Our results support that the theory of planned behavior can apply to secondary school students in urban areas. Furthermore, attitudes towards healthy food choices were the best predictor of behavioral intentions to engage in such choices in Inner Mongolian students.

Posterior reversible encephalopathy syndrome in a postpartum hemorrhagic woman without hypertension: A case report.

RATIONALE: Posterior reversible encephalopathy syndrome (PRES), which diagnosis is based on clinical symptoms and radiological features, is a neurotoxic disease characterized by a set of clinical manifestations, such as seizure, headache, visual, and/or consciousness disturbance. It is the first case of PRES followed by postpartum hemorrhage (PPH) without underlying disease. PATIENT CONCERNS: A 37-year-old healthy woman had PPH after caesarean section. Six days after delivery, headache occurred suddenly, followed by episodes of clonus seizure. DIAGNOSES: Brain computed tomography showed ischemic stroke. However, magnetic resonance imaging revealed characteristics consistent with PRES. INTERVENTIONS: The patient received phenytoin for seizure control. OUTCOMES: Seizure was under good control over the following days. Three months later, repeated magnetic resonance imaging showed complete remission. LESSONS: PRES may be triggered by PPH and is not necessarily secondary to typical predisposing factors such as hypertension or pre/eclampsia. Hormone fluctuation, increased blood pressure variation, and massive blood transfusion may be contributed to the development of PRES in our case. Also, it is necessary to rule out those life-threatening diseases, such as cavernoma hemorrhage, cerebral venous thrombosis, and ischemic stroke before the diagnosis of PRES.

Construction of a short form of the healthy eating behaviour inventory for the Japanese population.

INTRODUCTION: The present study constructed a short form of the Healthy Eating Behavior Inventory suitable for use in the Japanese culture (HEBI-J) and confirmed the scale's preliminary reliability and validity. METHODS: In Study 1, Japanese adults (N=75) completed a free-response questionnaire about healthy eating behaviours. Thematic analysis was used to identify three factors-balance, pattern, and restriction-associated with healthy eating behaviours and 12 items related to these healthy eating behaviours. In Study 2, Japanese office workers (N=784) completed two questionnaires regarding 12 items of healthy eating behaviours and the dietary stages of change. RESULTS: Confirmatory factor analysis demonstrated that the three-factor model was appropriate (GFI=.94, AGFI=.90, CFI=.90, RMSEA=.08, SRMR=.53). Reliability was confirmed by alpha coefficients and the Spearman-Brown formula. Concurrent validity was confirmed by the relationship between the healthy eating stages. CONCLUSIONS: This study demonstrated the preliminary reliability and validity of the HEBI-J.
