Effects of phytase supplementation on eggshell and bone quality, and phosphorus and calcium digestibility in laying hens from 25 to 37 wk of age.

Effects of dietary available phosphorus (aP) and Ca levels and an Escherichia coli 6-phytase supplementation were studied in Lohmann LSL-Lite hens from 25 to 37 wk of age. Eighty-four hens were used in a completely randomized design with 7 treatments. The treatments were a positive control (PC) diet with 0.45% aP, 3.70% Ca, and 0.16% Na from 25 to 28 wk and 0.38% aP, 3.73% Ca, and 0.15% Na from 29 to 37 wk; a negative control (NC) diet, similar to the PC diet, with 0.22% aP, 3.00% Ca, and 0.13% Na from 25 to 28 wk and 0.19% aP, 3.02% Ca, and 0.13% Na from 29 to 37 wk; the NC diets supplemented with phytase at 150 (NC + 150), 300 (NC + 300), 600 (NC + 600), or 1,200 (NC + 1,200) phytase unit (FTU)/kg; and the PC diet supplemented with phytase at 1,200 (PC + 1,200) FTU/kg. Hen performance, eggshell, and bone quality were measured on a 4-wk basis. Bone breaking strength and ash and apparent ileal digestibility (AID) of P and Ca were determined at 37 wk. One- and 2-way ANOVA were conducted, and Tukey's range test was used to compare multiple means where P ≤ 0.05. No differences in hen performance, eggshell quality, bone breaking strength, bone ash, and P digestibility were observed between the PC and the NC treatments. The NC hens had lower cortical (P < 0.001) and trabecular + medullary bone mineral density (P = 0.004) and total bone mineral content (P < 0.001) than the PC hens. The PC + 1,200 increased cortical bone mineral density (P < 0.001). The reductions of aP and Ca in the NC diet were not deficient for performance but had a minor impact on bone mineralization. The NC + 600 and NC + 1,200 increased AID of P (P = 0.024), and all phytase treatments except the NC + 150 increased AID of Ca (P = 0.010) compared with the NC diet.

Albuminuria in rural Thai people: a community-based screening with Combur Test and Micral Test strips.

OBJECTIVES: To identify albuminuria prevalence and examine the association of albuminuria with plasma glucose, blood pressure and body mass index in rural Thai people aged 35 and older. MATERIAL AND METHOD: All volunteer adults aged 35 and older at Ban Nayao, Chachoengsao Province were recruited in this cross-sectional study. Macroalbuminuria and microalbuminuria were tested in first morning urine using Combur and Micral Test strips. Fasting plasma glucose, blood pressure, weight and height were determined. Chi-square and multiple logistic regression analysis were used for analysis. RESULTS: Of the 357 participants, 26.61% had microalbuminuria, 3.08% had macroalbuminuria, and 9.2%, 19%, 7.3% had diabetes, hypertension, and obese, respectively. The prevalence of microalbuminuria and macroalbuminuria in people with diabetes were 30.30% and 15.15%, respectively. In the obese, the prevalence was 50% and 3.8% and was 30.88% and 7.35% in the hypertensive group, respectively. Strong significant associations between plasma glucose (p = 0.013), and body mass index (p = 0.008) with the progression of albuminuria were observed. According to multiple logistic regression analysis, diabetes and obesity were independent risk factors for albuminuria statistically significant (p = 0.036 and p = 0.005, respectively, 95% CI). CONCLUSION: The present study showed increased risk of albuminuria in diabetes and in obese people in a rural area of Thailand. Thus, community-controlled diabetes and weight program should be introduced to the rural community.

Dietary behaviors and nutritional status of adolescents in a remote rural area of Thailand.

INTRODUCTION: Nutritional status among adolescents is an important health indicator. The up-to-date information about nutritional status and food consumption pattern in the remote rural area is required for the effective public health intervention in the rural area of the country. The present study aimed to demonstrate the prevalence of malnutrition, eating behavior and nutritional knowledge among secondary school students in a remote rural area in Thailand. MATERIAL AND METHOD: Body weight and height data were collected from 298 secondary school students for nutritional status calculation using the Institute of Nutrition Research, Mahidol University, INMU-Thaigrowth program. Eating behavior and nutritional knowledge were observed by self-administrated questionnaires. RESULTS: The prevalence low height-for-age (<-2SD) 6.1% and it was 0.7% for low weight-for-height (<-2SD). Fruits (69%) and vegetables (79.4%) consumptions were in the high level. The authors found that the students always consumed commercial snacks especially salted chips more often than regular Thai dessert (74.0% VS 52.3%). The inappropriate behavior found in the present study included always drinking caffeine beverage (43.5%), always drinking alcoholic beverage (6.5%) and always consuming instant noodles (64.4%). CONCLUSION: The prevalence of malnutrition was low among this population. The studied population had a fair knowledge about nutrition. The authoes found that regular consumption of highly commercialized snack products especially salted chips and instant noodles were at a high level in this remote rural area of Thailand. The pattern of nutritional problems in Thailand may have changed in which a public health program for children in rural areas of the country should recognize this transition.
