Nutrition Knowledge of Elderly and Middle-age Urban Population and Its Effects on Diet Quality and Dairy Consumption: A Cross-sectional Study in Eight Cities of China (P10-060-19)

ObjectivesThe main aim of the present study was to investigate the nutrition knowledge and diary knowledge of elderly and middle-aged urban community-dwelling population, and their effects on diet quality and dairy consumption. MethodsData shown in present study was extracted from a cross-sectional survey, the Chinese Urban Adults Diet and Health Study, conducted in eight cities from March to July, 2016. Data were collected from subjects by trained interviewers using an interviewer-administered questionnaire in two parts related to social-demographic factors and knowledge, attitude, and practice (KAP). For knowledge, seven questions and six questions were used to measure subjects’ knowledge towards nutrition and the health benefits of dairy products, respectively. One-time 24-h dietary recall and the semi-quantitative Food Frequency Questionnaire (semi-FFQ) for one recent month were used to investigate the food consumption with the help of a standard reference picture book, bowls, plates, and spoons. China Healthy Diet Index (CHDI) and Dietary Diversity Scores (DDS) were used to measure dietary quality. Covariates were determined by questionnaires and interviews. ResultsA total of 1090 individuals aged 62.12 ± 8.62 (range 45–81 years) were included, 60.8% were female. Males, subjects with lower household monthly income and lower education level had significantly lower knowledge scores. Participants with better nutrition knowledge had significantly higher CHDI score (63 vs 54, P < 0.05) and DDS score (6.3 vs 5.7, P < 0.05) when compared to subjects with poor nutrition knowledge. The multivariate logistic regression model in Table 1 illustrated that, after adjusting for age, gender, education level, household income and lactose intolerance symptoms, a significantly increased rate of no dairy consumption was observed among participants with poor nutrition knowledge (OR = 2.5; 95%:1.4 to 4.2) and participants with poor dairy knowledge (OR = 3.1; 95%:1.5 to 6.5). ConclusionsThe findings of this study indicated that knowledge gaps surrounding nutrition and dairy products exist in Chinese elderly and middle-age urban population. Moreover, good command of nutrition knowledge and dairy knowledge has a positive effect of dietary quality and milk consumption rate.

Trends in the Attack Rates, Incidence, and Mortality of Stroke during 1986–2012: Data of Kaunas (Lithuania) Stroke Registry

BackgroundThere is a lack of reliable epidemiological data on longitudinal trends in stroke attack rates, incidence, and mortality in the countries of the Baltic region.AimsThe aim of the present study was to explore the longitudinal trends of stroke in middle-aged urban population of Lithuania during the period of 1986 through 2012.MethodsAll stroke events in the studied population were ascertained and validated according to the standardized criteria outlined by the WHO MONICA Project. The study included all patients in Kaunas (Lithuania) city aged 25 to 64 years who experienced a stroke between 1986 and 2012. Estimates of time-trends of the annual percentage change in stroke attack rates, incidence of stroke, and mortality from this condition were made by applying the Joinpoint regression analysis.ResultsDuring the study period, 9,992 stroke events were registered. The overall proportion of recurrent events was 25.7%. Overall, 18.9% of the events (20.0% in men, and 17.4% in women) were fatal within 28 days. During the period of 1986 to 2012, a flat trend in the incidence of stroke was observed among both male and female middle-aged inhabitants of Kaunas city, while attack rates were increasing due to the increase in recurrent strokes. Both mortality and 28-day case fatality of stroke declined significantly over the study period in both sexes.ConclusionsAn increase both in the incidence and recurrence of stroke among middle-aged men residing in Kaunas city and in the recurrence of stroke among women denotes the inefficiency of measures applied both for primary and secondary prevention of stroke in Lithuania. The revision of current prevention strategies and the introduction of new ones are of paramount importance in order to fight the epidemic of stroke.

Dyslipidemia and its risk factors among urban middle-aged Iranians: A population-based study

AimsDyslipidemia is a known risk factor for cardiovascular disease and is a leading cause of mortality in developed and developing countries. This study was aimed to determine the prevalence of dyslipidemia and its risk factors in an urban group of Iranian adult population. MethodsIn this study, based on the criteria set by the National Cholesterol Education Program, the prevalence of dyslipidemia was evaluated in a population of 4737 people aged 45–69 years who participated in the second phase of an ophthalmology cohort study in Shahroud. Dyslipidemia prevalence was determined by age, sex, and risk factors of the disease; the findings were tested by using simple and multiple logistic regression. ResultsThe prevalence of dyslipidemia was 66.5% (CI 95%: 64.4–68.6) in males, 61.3% (CI 95%: 59.5–63.2) in females, and 63.4% (CI 95%: 62.0–64.9%) in both sexes. The prevalence of hypertriglyceridemia, hypercholesterolemia, low HDL-C, and high LDL-C, respectively, was 28.8%, 13.4%, 42.3%, and 13.4%, respectively. In multivariate logistic regression model, increase of age (for females), abdominal obesity, overweight and obesity, hypertension, and diabetes were associated with an increased odd of dyslipidemia. ConclusionThe prevalence of dyslipidemia in middle-aged urban population in Iran is high, and with increasing age there is an increased risk of dyslipidemia. Hence, considering the growing trend of aging in Iran, there is need for taking special measures to deal with dyslipidemia as a health priority. Furthermore, the need for planning in order to reduce the risk of dyslipidemia and prevent its complications is greater than ever.

Trends in health indicators in the urban middle-aged population in the Czech Republic in 1998–2010

ObjectivesTo track the trends in general health indicators and the prevalence of cardiovascular diseases (CVD), high blood pressure and elevated blood cholesterol in the middle-aged urban population in the Czech Republic in 1998–2010. Study designCross-sectional study. MethodsThe following data from the three-phase HELEN (HEalth – Lifestyle – ENvironment) study, a prevalence questionnaire survey, were analysed: data collected from 8214 subjects in phase I, 6107 subjects in phase II, and 4389 subjects in phase III. The study subjects were aged 45–54 years and the study period spanned from 1998 to 2010. The differences in the indicators between phases were evaluated by binary and ordinal logistic regression models at a significance level of 0.01. ResultsOver the study period, a significant increase was observed in the proportion of respondents who self-rated their health as very good or good: from 46.6% to 51.0% in males (P = 0.006) and from 45.5% to 49.9% in females (P < 0.001). At the same time, the rates of respondents under long-term medical follow-up rose significantly from 36.3% to 44.3% (P < 0.001) and from 46.4% to 56.2% (P < 0.001), respectively.CVD prevalence did not change although the percentage of males and females with high blood pressure (from 29.3% to 36.6% and from 26.0% to 31.2%, respectively) and elevated total cholesterol (from 29.0% to 36.6% and from 27.3% to 32.4%, respectively) increased significantly. ConclusionsSelf-rated health among the middle-aged population in the Czech Republic improved during the 1998–2010 period, but, at the same time, more people needed to be followed up for a disease. The proportions of respondents with hypertension and elevated blood cholesterol increased while the CVD rates did not vary significantly.

Abstract P398: Uric Acid And Prehypertension: Salt Intake in Addition to Insulin Resistance are not Mediators.

Introduction: The association "uric acid and high blood pressure" is still matter of debate. Therefore, to distinguish serum uric acid as an independent factor for high blood pressure can start new trials to prevent hypertension. A paleoantropological rationale for this association was a knockout of uricase occurred during the Miocene among hominids that induced high levels of uric acid. As consequence, during food shortage times, high uric acid had an evolutionary benefit increasing salt-sensitivity for keep blood pressure and rising insulin resistance that maintaining high blood glucose levels provided fuel for the brain. Nowadays, the average levels of uric acid are substantially higher compared to chimpanzees, a uricase-deficient primate, and among remote populations as the yanomamo. Hypothesis: we assessed the hypothesis that the link between uric acid and blood pressure in individuals without hypertension is independent of sex, age, race, salt and alcohol intakes, glucose homeostasis, body-mass index and renal function. Methods: from the 15105 participants of the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) aged 35-74 years, we selected 7954 individuals (median age = 48 years-old; women =58.1; White = 56.6%) without hypertension, diabetes, previous cardiovascular diseases. The presence or not of prehypertension (7th JNC criteria) was the dependent variable and quartiles (Q) of serum uric acid, the independent variable. We applied an unconditional logistic regression adjusted for age and sex. After this, according to our hypothesis, we added the following variables: (1) 24-hour urinary sodium; (2) log Homeostasis Model Assessment (fasting blood glucose (mg/dL) х fasting insulin (mg/dL)/450), and (3) a full model, adding race, body-mass index, alcohol intake, and glomerular filtration rate by CKD-epi). Results: the uric acid quartiles ranges (md/dL) were Q1 ≤ 4.1; Q2:4.2-5.0; Q3:5.1-6.0; Q4: ≥ 6.1 and the number of participants were Q1= 1909; Q2=2029; Q3=2000; Q4= 2016. Considering Q1 as reference, the age-sex adjusted odds ratios (95% Confidence Interval) through the quartiles were: Q2= 1.22 (1.05-1.41); Q3= 1.40 (1.20-1.63); Q4= 2.03 (1.71-2.39) [P for trend &lt;0.001]. Adding 24 hour urinary sodium, the ORs (95% CI) were: Q2= 1.19 (1.01-1.40); Q3= 1.37 (1.16-1.62); and 1.94 (1.61-2.33) [P for trend &lt;0.001]. Adding HOMA-IR, the ORs (95% CI) were: Q2= 1.14 (0.97-1.34); Q3= 1.25(1.05-1.48); and Q4=1.62(1.34-1.96) [P for trend &lt;0.001]. Finally, for the full model the ORs were Q2= 1.04 (0.88-1.23); Q3= 1.05 (0.88-1.26) and Q4= 1.32(1.08-1.62) [P for trend &lt;0. 01]. Conclusion: Uric acid levels were correlated to prehypertension among a middle-aged urban population. It occurred independently of other variables classically associated to high blood pressure or the origin of higher uric acid in hominids.

Relation between Cataract and Metabolic Syndrome and Its Components

To estimate the prevalence of cataract in the middle-aged urban population and the relation between cataract and metabolic syndrome and metabolic syndrome components. The survey was carried out in Kaunas City, Lithuania, from 2001 to 2002, according to WHO MONICA study protocol. The ophthalmologic investigation was performed for 1282 respondents (573 men and 709 women) aged 35-64 years. Cataract was defined at slit lamp using LOCS III method. Metabolic syndrome was defined by ATP III criteria. Cataract was found in 17.6% of men and 19.0% of women (p>0.05). Metabolic syndrome was detected in 19.5% of men and 25.7% of women (p<0.05). After distribution of persons into 10-year age groups (35-44, 45-54, 55-64), the prevalence of cataract and metabolic syndrome among men and women significantly increased with age. A relation between cataract and metabolic syndrome was found for men aged 55-64 years and for women aged 45-64 years: the prevalence of cataract in men with metabolic syndrome was 1.3 times higher (43.8% vs 32.9%; OR=1.59 [95% CI, 0.77-3.26]) and in women with metabolic syndrome 1.4 times higher (31.8% vs. 22.6%; OR=1.60 [95% CI, 1.03-2.49]) than in persons of the same age and sex without metabolic syndrome. For men aged 4-64 years cataract was significantly related to central obesity (OR=1.80 [95% CI, 1.01-3.20]) and for women aged 45-64 years cataract was significantly related to higher arterial pressure (OR=1.98 [95% CI, 1.21-3.25]), central obesity (OR=1.54 [95% CI, 1.01-2.35]), and elevated level of serum triglycerides (OR=1.86 [95% CI, 1.20-2.90]). The results of this study show that the prevalence of cataract in urban women 45-64 years of age with metabolic syndrome was significantly higher than in women of this age without metabolic syndrome.

Early Age-Related Maculopathy and Risk Factors of Cardiovascular Disease in Middle-Aged Lithuanian Urban Population

To assess the prevalence of age-related maculopathy (ARM) in a middle-aged urban population and the relationship between ARM and the main risk factors of cardiovascular disease (CVD). The survey according to the WHO MONICA study protocol was carried out in Kaunas city, Lithuania, from 2001 to 2002. A total of 1403 persons aged 35 to 64 years were screened (626 men and 777 women: response rate 62.4%). Ophthalmologic investigation was performed for 1337 respondents (594 men and 743 women). Analysis of the relationship between ARM and risk factors of CVD was performed in case-control subdivision matching for sex, age, and education level. Early ARM was diagnosed in 7.4% of men and 5.4% of women. Rate of current smoking in case and control groups did not differ in men but in case group of women it was greater than in control group. Mean systolic and diastolic blood pressure and body mass index (BMI) in male case group and mean fasting blood glucose concentration in female case group were higher than in corresponding control groups. Frequency of diastolic hypertension (diastolic blood pressure > or = 90 mmHg) and obesity (BMI > or = 30 kg/m2) in male case group was higher than in control group. ARM was not associated with cholesterol and triglyceride levels in men and women. Early ARM in middle-aged Lithuanian urban population was associated with current smoking in women but not in men; it was associated with diastolic blood pressure and BMI in men and with fasting glucose level in women.
