Diet intervention according to Trans-theoretic Model in young and middle-aged patients with asymptomatic hyperuricemia / 中国实用护理杂志

Objective To study intervention effect of diet habits according to Trans-theoretic Model (TTM) in young and middle-aged patients with asymptomatic hyperuricemia. Methods 120 patients were divided into the intervention group (n=60) and the control group (n=60). The nursing intervention by stages of TTM was implemented to a total of 56 patients in the intervention group in the study. Routine nursing care was taken to 57 patients in the control group. Patients were evaluated by self-designed questionnaire after 1, 3 and 6 months of the intervention in the two groups respectively, including the diets of patients, the change of patients′ eating habit, differences of uric acid, total cholesterol, triglycerides, blood sugar. Results The patients′ intake of beer, seafood, meat, edible oil in the intervention group was lower than the patients′ intake in the control group, while the patients′ intake of fruits and vegetables was higher than the patients′intake in the control group after 1, 3 and 6 months of the intervention, which was statistically significant ( P < 0.01). Compared with 27 cases in the control group, 53 cases in the intervention group were in action phase and maintenance phase after 6-month intervention, the difference was statistically significant (P < 0.01). After six months′intervention, the patients′uric acid, triglycerides in the intervention group was (418.01 ± 24.15)μmol/L and (1.52 ± 0.56) mmol/ L respectively, which was significantly lower than (435.02 ± 26.35) μmol/ L and (2.45 ± 0.74) mmol/L in the control group, t values were-3.47 and 2.20 respectively, P<0.01. Conclusions Diet intervention based on the TTM can effectively promote the change of patients′ unhealthy eating habits, improve self-management skills, and reduce uric acid, which is worthy of generalizing.

Diet, size and reproductive biology of the silver catfish, Chrysichthys nigrodigitatus (Siluformes: Bagridae) in the Cross River, Nigeria

The silver catfish, Chrysichthys nigrodigitatus (Lacépède: 1803) is a highly valued food-fish included among the dominant commercial catches exploited in major rivers of Africa. To provide useful biological data for management, samples were collected monthly between January (2005) and December (2007) in three zones: I: Upper Cross River (grassland), II: Middle Cross River (mixed forest and grassland), and III: Lower Cross River (rainforest)] along 200 km length of the Cross River, Nigeria. Data from 1 248 specimens were processed using: allometric coefficient (b), gonado-somatic index, Fulton’s condition factor and diversity indices. Male dominance was observed in all populations; C. nigrodigitatus reached maturity at 11.5cm (male) and 16.7cm (female) total length. Gonado-somatic index was higher for females with a peak in the early rains. The breeding period was between April and August with mean fecundity ranging between 4522 ±1924 eggs and 20321 ± 5543 eggs. This was directly related to total length and weight by the regression models: F = 2365.88 + 560.22 log L and F = 5025.81 +56.34 log W respectively. Exponential equations for length-weight relationships were Wt=-1.997 Lt2.206 (Zone I), W = -2.831 Lt3.040 (Zone II) and Wt= -2.245 Lt2.995 (Zone III). The mean allometric coefficient (b) showed significant departure from cubic value (negative allometry) for Zone I while Zones II and III showed no difference, indicating isometry. Dominant items in the diet were fish and fish parts constituting 21.6% with Food Richness and Gut Repletion Index of 18 and 100% respectively, in all zones. Diet Breadth of 0.802 (Zone I), 0.922 (Zone II) and 0.910 (Zone III) indicate a high trophic flexibility that enables switching from one diet to another according to availability. Mean condition factor for males varied from 0.718 ±0.117 minimum in Zone I to 0.996 ±0.062 maximum in Zone III. Forest inland wetlands (Zone II and III) of Cross River provided better condition for C. nigrodigitatus. Rev. Biol. Trop. 56 (4): 1785-1799. Epub 2008 December 12.

The Survey of the Relationship of Diet Habits and Health Consciousness with Essential Hypertension in the Rural Residents / 中国慢性病预防与控制

Objective To investigate the relationship of diet habits and health consciousness with essential hypertension in the rural residents of different economic levels in Hebei Province. Methods Cases aged 35-year old and over from Jizhou,Hebei province were selected by means of random stratified sampling in different economic levels. Results The crude prevalence rates were 44.93% in lower economic level and 36.55% in higher economic level. There were significant differences in prevalence rates of hypertension between the different economic levels(?2=31.846,P
