本研究是評估某職場員工的營養知識與飲食行為的情形及健康促進之營養教育介入計畫成效的評估。材料與方法:(1)問卷包括基本資料、營養知識、飲食行為及其影響因素(外在行動線索、障礙因子、正向健康動機及自我效能等四項),共回收662份(回收率66%)。(2)舉辦均衡飲食園遊會宣傳營養教育課程,共計21人參加但最後只有8人全程參與,其餘13人未完成。結果:(1)男性260名,女性402名,年齡層以26~35歲占主要部分(68%),男性教育程度、年齡明顯高於女性,女性無運動習慣的比例較高,而抽煙及喝酒比例較低。員工們普遍認為電視(佔36.0%)是影響健康概念的主要因素但教育程度高的男性則以網路為主。一般營養知識平均0.62±0.18、對食物中纖維及脂肪含量認知平均為0.67±0.23和0.66±0.23、心血管疾病危險因子的認知平均為0.56±0.16。以上的平均分數皆是男性高於女性(0.63±0.19 vs 0.62±0.18;0.69±0.21 vs 0.66±0.24;0.70±0.24 vs 0.64±0.22;0.56±0.16 vs 0.55±0.17),但女性的飲食行為較男性好(3.34±0.38 vs 3.30±0.38),除性別外,年齡和教育程度也影響員工知識及行為表現。障礙因子與其營養知識及飲食行為的相關性最低,自我效能與『取代的飲食行為』有最高的相關性(r=0.603,P<0.01),但其與一般知識的相關性不高(r = 0.201,P<0.01)。(2)全程參與的8人在營養教育介入後的知識與飲食行為有正向增加(P>0.05),自我效能下降,但無統計上差異。結論:員工營養知識平均0.62±0.18,約7成不知性別和血糖值也為心血管疾病的危險因子。員工在修飾的飲食行為上表現最差,健康動機偏向靜態活動。影響員工飲食障礙因子有外食、時間和正確的忠告等方面,自我效能平均分數1.16±0.36。而此次參與營養介入的員工在教育前即有良好的營養知識及飲食行為故在營養介入後進步的空間有限,無法看見明顯的成效。
This study assessed the nutritional knowledge、dietary practices, and nutrition intervention project of employees at worksite. The questionnaire included demographic characteristics, nutritional knowledge, dietary practices and the psychosocial items (social support, barriers to health diet, belief in diet-disease connection, and self-efficacy for healthy diet). Six hundred sixty-two respondents completed the study, twenty-two participated the nutrition education program, and eight person completed program. There were 260 males and 402 females; average age was 30 years old, The man had higher education and age than women. About 58% of men and 74% of women did not exercise regularly. The mean score nutritional knowledge was 0.62±0.18 and knowledge of fiber and fat content in food were 0.67±0.23 and 0.66±0.23. The man had better mean scores than women. The women had higher average scores of avoiding and replacing dietary practices than men. Watching TV is the main resources of health. There were statistically significant positive associations between self-efficacy and dietary practices (r=0.516, P<0.01). Multiple regression model, self-efficacy explained 26.5% of the variance in dietary practices. Employees who participated in the nutrition education program increased their nutrition knowledge and dietary practices, but not significant.
