Berggren3 , S. Bergstr¨ om4 . 1 Clinical Nursing Science, Kristianstad University College, Kristianstad, Sweden; 2 King Khalid University, Abha, Saudi Arabia; 3 Kristianstad University College, Kristianstad, 4 Karolinska Institute, Stockholm, Sweden Rationale: This study explores the prevalence of low and high BMI in a Saudi Arabian hospital (SAH) and compares figures with previous studies from Sweden (1) (n = 2170) and Iceland (2) (n = 92). Comparisons are made between male and female patients in the Saudi Arabian hospital. Methods: In the Saudi Arabian hospital 177 (76%) agreed to participate, 115 men and 62 women. Low BMI: BMI <20 if 69 yrs and <22 if 70 yrs. Overweight: Caucasian OR Asian BMI 25 OR 23 if 69 yrs, 27 OR 25 if 70 yrs. Obese: Caucasian OR Asian BMI 30 OR 28 if 69 yrs, 32 OR 30 if 70 yrs. Results: The prevalence of low BMI (16%) was similar as in Swedish hospitals (17 22%) and in the Icelandic hospital (14%). According to Asian cut-offs obesity was more common in the Saudi Arabian hospital (29%) than in Sweden (11 16%) and Iceland (24%) but simlar or somewhat lower if using Caucasian cut-offs (12%). In the Saudi Arabian hospital 25% of the women and 22% of the men had a low BMI (ns). Significantly more women (28 OR 39%) than men (11 OR 23%) were obese (Caucasian OR Asian cut-offs). Conclusion: Health care needs to make efforts to prevent or initiate treatment for both under- and overweight/obesity as these conditions are prevalent, and obesity is more prevalent in women than in men.

PP136 HYPOVITAMINOSIS D IN HEALTHY THAIS IS ASSOCIATED WITH DECREASED RISK OF HYPERTENSION K. Sumriddetchkajorn1 , L.-O. Chailurkit2 , A. Thakkinstian2 , P. Sritara2 . 1 Human Nutrition, Mahidol University, Institute of Nutrition, Salaya, Nakhon Pathom, 2 Mahidol University, Ramathibodi Hospital, Bangkok, Thailand Rationale: Low serum levels of 25-hydroxyvitamin D [25(OH)D] are associated with hypertension. Hypovita-

Poster presentations minosis D has been observed in tropical regions, but there was no data on its association with hypertension. Methods: A matched case-control study was conducted on participants from a cardiovascular study. Plasma 25(OH) D levels in 1985 from randomly selected 137 cases and controls were used to determine vitamin D status and calculate the odd ratios (OR) of having hypertension in 1997. Serum 25(OH)D 28 ng/dL was used as a cutoff value. Cases and controls were matched for age and gender. Body mass index (BMI), HDL, LDL, triglyceride were used as covariates. Results: 36% of the participants had suboptimal 25(OH)D level. Controls had a significantly higher proportion of vitamin D deficiency than cases. Adjusted for matching variables, the odd ratios (OR) of having hypertension were marginally significant for hypovitaminosis D (OR, 0.59; 95% CI, 0.35 0.99; p = 0.05) but statistically significant for higher BMI (OR, 2.07; 95% CI, 1.12 3.83; p = 0.02). The OR of having hypertension for hypovitaminosis D was slightly attenuated but remained marginally significant after further adjustment for BMI, HDL and triglyceride (OR, 0.58; 95% CI, 0.34 0.99; p = 0.05). Stepwise regression identified BMI as the only variable of significance in relation to hypertension. Conclusion: Although not a rarity in Thailand, hypovitamonisis D was associated with decreased risk of hypertension in Thais. Disclosure of Interest: None declared

In hospitals, however, the majority of undernourished patients has a suboptimal protein and energy intake. The aim of this study was to investigate predictors for achieving protein and energy requirements on the fourth day of admission in undernourished hospitalized patients. Methods: 830 adult undernourished patients (SNAQ  3) admitted to the Franciscus Hospital in Roosendaal in 2008 were retrospectively included. Data were collected on medical and nutrition related factors during the first four days of hospital admission and on protein and energy intake on the fourth day of admission. Intake requirements were defined as 1.2 g protein per kg body weight (weight adjusted when BMI > 27) and 100% of the energy requirement based on calculated resting energy
