探討人格特質與健康狀況和蔬果攝取之相關性
Exploring of the Relationship between Personality Traits, Health Status and the Intake of Fruits and Vegetables
摘要
本研究之目的主要在探討不同人格特質與蔬果攝取、抗氧化力和氧化傷害指標等之相關性。本研究分兩部份進行，前導性試驗是利用台灣2004 ~ 2008 年國民營養健康狀況變遷調查 (NAHSIT 2004~2008) 之結果進行數據分析，選取19歲以上有回應問卷並完成體檢之成年人之資料共1,731 人，排除資料不足者後共 1,616 位，將受試者依出生月日之星座分為四組以進行分析。實測觀察為一橫斷面試驗設計，以 139 位 20~50歲成人之數據進行分析。試驗當天受試者須進行體位測量，填寫綜合問卷和蔬果攝取頻率問卷，並採集血液樣本測定抗氧化狀態和氧化傷害指標。此外，以星座特質和 FFM 特質問卷將受試者分別分類為火、水、風、土象四組和神經質、外向性、開放性、友善性、謹慎性五種特質以進行相關性分析。前導性試驗結果顯示，所有受試者平均每週攝取 2.9 次蔬菜和 1 次水果，在四組間無顯著差異。不符合代謝症候群危險因子指標之人數在四組間無顯著差異。實測觀察結果顯示，所有受試者平均每日攝取5.48 份總蔬果，其中女性風象組之總蔬果攝取量顯著高於水象組；開放性特質與總蔬果、蔬菜和水果攝取量呈顯著正相關性。抗氧化力方面，血漿中總多酚濃度為風象組顯著高於其他三組，但 FRAP (Ferric-reducing antioxidant power) 和血液中維生素C濃度四組間無顯著差異。氧化傷害指標血清 MDA (Malondialdehyde) 濃度方面，火象組顯著高於其他三組，但 PC (Protein carbonyl) 四組間無顯著差異。對於蔬果攝取，風象組最易受媒體影響，顯著高於水和土象兩組，且易受心情影響，顯著高於火和水象組。綜合以上的結果顯示，本身的特質和外在環境均可能會影響蔬果的攝取，尤其對風象組影響較大。而增加蔬果攝取量之同時，也可增加體內抗氧化力和降低氧化傷害。建議未來在推廣和鼓勵多攝取蔬果時，應針對不同特質設計不同的衛教方式，以達到攝取足夠蔬果量之目標。

This study was to investigate the relationship between different personality traits, their choices of fruits and vegetables (FV) and the biomarkers of antioxidative capacity and oxidative damage. The study consistede of two parts. Pilot study to analyze the database of 2004 to 2008 National Nutrition and Health Survey of Taiwan (NAHSIT 2004 ~ 2008). 1,616 subjects were included for the analysis of data. Experimental obseration: 139 subjects aged 20~50 years were included in this study. During the experiment, subjects were required to measure the body weight and fill out the questionnaires regarding their basic information, the attitude toward the intake of FV, as well as their lifestyle and frequency of FV intake for the previous month. 15 ml of blood samples were colllected to analyze antioxidative capacity and oxidative damage. Subjects were divided into four or five groups according to their constellation or FFM (Five factor model), respectively. The groups were as follows: constellation - fire signs (FS), water signs (WS), air signs (AS) and earth signs (ES). FFM - Neuroticism (N), Extraversion (E), Openness, (O), Agreeableness ( A ), Conscientiousness (C). The results of pilot study, the average weekly intake of vegetables and fruits were 2.9 times and 1 time. The risk factors of metabolism syndrome (MS) were no significant between four groups. The result of experimental obseration, the average daily intake of total FV was 5.48 servings, the total FV intake of women in AS group was significantly higher than that in the WS group. Openness was positive associated with the intake of vegetables, fruits and total FV significantly. The plasma level of total polyphenols in the AS group was significantly higher than those in the other three groups. The serum level of malondialdehyde (MDA) in the FS group was significantly higher than those in the other three groups. The influence of media on the eating behavior of FV in AS group was significantly bigger than those in the WS and ES group; the influence of mood in AS group was significantly higherthan those in the FS and WS group. These results suggest that the intake of FV is affected by different personality and the environment, especially in the AS group, and will intake more FV, followed by a increased plasma level of polyphenols and a decreased serum level of MDA.
