Quantitative Research on Gifted/Talented Students’ Critical Thinking Skills

This study aims to determine the level of critical thinking skills among gifted students and investigate whether there is a relationship between their levels of critical thinking and their gender, age, grade level, pre-kindergarten education and parents' educational backgrounds. The study sample of the research consists of 203 students who are enrolled in the Science and Art Center in the central district of Kütahya province, Turkey during the 2021-2022 academic year. As per the findings, gifted female students have higher mean scores in the Critical Thinking Dispositions Scale compared to gifted male students. Also, this study examined the differences in critical thinking levels between gifted students who received pre-kindergarten education and those who did not receive pre-kindergarten education. The results indicate that these differences are statistically insignificant. As another remarkable finding, gifted students whose mothers have a high school or Master’s and above education level have significantly higher levels of critical thinking compared to gifted students whose mothers have a primary school or middle school education level.

Comprehensive nursing model for diabetic foot ulcers: A strategy to improve prognosis and quality of life.

Diabetic foot (DF) ulcer is one of the common complications of diabetic patients, with high incidence and amputation rate, which seriously affects the quality of life and health of patients. Therefore, how to effectively prevent and treat DF ulcers and reduce amputation rate has become an urgent problem in the medical field. As a comprehensive nursing model for patients with DF ulcers, comprehensive nursing intervention is designed to improve the therapeutic effect and prognosis and reduce the rate of amputation. Convenient sampling method was used to select 360 patients with DF who received routine care for DF ulcers from July 2013 to July 2023 for retrospective cohort analysis. According to the existence of exposure factors (comprehensive nursing intervention), 180 cases were divided into observation group and comparison group. The basic demographic data, amputation rate, severity of foot ulcer, neuropathy and vascular disease, and blood glucose control were compared between the 2 groups. The data was analyzed using SPSS26.0. Harman single factor test was used to check whether there was common method bias in the study data. Descriptive analysis, Spearman rank correlation analysis and multiple linear regression analysis were used to analyze the current situation of amputation rate of DF patients and the influence of comprehensive nursing intervention on the amputation rate of DF patients. The amputation rate was 2.8% in the Observation group compared to 8.3% in the Comparison group. The amputation rate of the observation group was generally higher in the age group, and the amputation rate of the observation group was higher in the middle school education level and below and the economic status of <5000 yuan. The difference was statistically significant (P < .05). Age (odds ratio [OR] = 1.96; 95% confidence interval [CI]: 0.88-4.38), education level (OR = 1.30; 95% CI: 1.69-6.46), economic status (OR = 2.28; 95% CI: 1.69-10.85) was an independent risk factor for amputation rate (P < .05). Comprehensive nursing interventions have played a positive role in reducing the rate of amputation in patients with DF.

Examining the Effects of Social Media on Mental Health Among Adolescents in Saudi Arabia.

Adolescents are immersed in a highly advanced technology setting, characterized by extensive availability of personal devices, the internet, and other social media platforms, which greatly impact their mental development. Concerns arise around potential negative consequences, including social isolation, internet addiction, exposure to improper content, depression, cyberbullying, and sleeping difficulty. The impact of social media on the mental well-being of adolescents has emerged as an escalating concern. The continuous exposure to carefully selected content, online harassment, and the expectation to comply with unrealistic standards all contribute to the development of depression and anxiety.This research aims to explore the impact of social media on the mental health of adolescents in the Saudi Arabian context. This online cross-sectional study was conducted on Saudis aged 10 to 24 years old who have social media accounts in Saudi Arabia between August and November 2023. Binary logistic regression analysis was conducted to identify factors that make the study participants more likely to be mentally affected by social media. A total of 2856 participants were involved in this study. The most commonly used social media platformby the study participants was Twitter (30.3%). The majority of the study participants (77.4%) reported that they have tried to reduce their social media usage for mental health reasons. The most commonly agreed-upon statements were that "they feel that excessive social media use has negatively affected their sleep patterns,""they often sleep late in the night because of social media usage,"and "they check their social media account before they sleep in the night," accounting for 71.0%, 66.1%, and 58.3%, respectively. Overall, the study participants showed a low level of being mentally affected due to social media with a mean score of 7.8 (SD: 3.9) out of 21, which is equal to 37.1%. Older participants (aged 16-24 years) were more prone to be mentally affected due to social media compared to younger ones (aged 10-15 years; p < 0.05). On the other hand, participants who were married, had a middle school education level, or lived in the northern, western, or eastern regions were less likely to be mentally affected due to social media compared to others (p < 0.05). The study participants showed a low level of being mentally affected due to social media. Individuals in the 16-24 years age group show a higher susceptibility to mental impacts resulting from social media usage. The primary duty for reducing the potential negative effects of social media should not rest only on parents and caregivers. Advocating for the creation of technology-free zones and fostering in-person friendships among teens could be a beneficial approach that policymakers should support.

Impact of the eHealth literacy, knowledge and attitudes on COVID-19 prevention behavior among residents in the second year of the COVID-19 pandemic: A cross-sectional study in Anhui Province, China.

The pandemic of COVID-19 continues to challenge people's health worldwide. In the second year of the pandemic, adherence to COVID-19 preventive behavior is key to continuing efforts to overcome the epidemic. This study aims to assess the COVID-19-related knowledge, attitude, and prevention behavior (KAP) and electronic health literacy (eHealth literacy) among Anhui residents in China. From January 30 to March 27, 2021, the cross-sectional study was performed among Anhui residents in China, including 16 cities. An online survey was adopted to assess KAP regarding COVID-19, and eHealth, involving a total of 2,122 citizens. Following informed consent, residents were recruited by convenience sampling. Frequencies and proportions were calculated. Additionally, Mann-Whitney U tests were used to analyze the variables. Independent predictors of preventive behavior of COVID-19 were ascertained using a multivariable logistic regression model. Residents demonstrated good knowledge, positive attitudes, acceptable practices, and good eHealth literacy. Online news and WeChat are the main health information resources. Citizens who had good knowledge, a positive attitude, good eHealth, and did not participate in the online lectures or training COVID-19 were more likely to take preventive measures. Those with poor health, who were male, did not have family members working in health care facilities, and did not work in a face-to-face environment were less likely to take precautions. Compared with a master's degree and above, participants with middle school education level and below took preventive behavior sometimes. Residents who browse the COVID-19 webpage <15 min weekly seldom took preventive actions. The study showed that in the second year of the COVID-19 pandemic, Chinese residents had adequate knowledge of COVID-19, positive attitudes, appropriate preventive practices, and basic eHealth literacy. To prevent the rebound of the COVID-19 epidemic, the government and health agencies should inform citizens concerning which information channels or websites to use and assist the underprivileged population who lacks basic infrastructure. In addition, increasing the level of knowledge and attitude, enhancing eHealth literacy and the Health Belief Model (HBM), and implementing the Health Code were seen as ways to reinforce adherence to preventive behavior. Targeting men, implementing public awareness campaigns, community engagement strategies, and health education programs are recommended.

Association of adherence measured by self-reported pill count with achieved blood pressure level in hypertension patients: a cross-sectional study

BackgroundMedication adherence plays an essential role in controlling blood pressure to reduce morbidity and mortality of hypertension disease. Thus, this study aimed to determine the association of medication adherence measured by self-reported pill count with blood pressure levels among patients at several community health centers in Surabaya.MethodsAdherence was assessed using the pill count method by comparing the total number of antihypertension drugs taken with the prescribed drugs. The inclusion criteria involved hypertensive patients who received antihypertension drugs, specifically adults and elderly, except the pregnant woman. The patient blood pressure was measured by healthcare workers in the targeted community health centers. Descriptive and multivariable logistic regression analyses were performed to assess factors associated with medication adherence with blood pressure levels.ResultsA total of 264 hypertensive outpatients participating in this study, 77.65% of participants were adherent to antihypertensive drugs based on the pill count method, and 40.91% of participants had controlled blood pressure. Patients with uncontrolled blood pressure were about six times (adjusted odds ratio [AOR]: 6.15; 95% confidence interval [CI]: 2.694–14.039; P = 0.000) more likely to have non-adherent medication than patients with controlled blood pressure. Reciprocally, non-adherent participants (pill count < 80%) were about six times (AOR: 6.081; 95% CI: 2.672–13.838; P = 0.000) more likely to have uncontrolled blood pressure compared to adherent patients (pill count ≥ 80%). Age less than 40 years old (AOR: 5.814; 95% CI: 1.519–22.252; P = 0.01) and having middle school educational level (AOR: 0.387; 95% CI: 0.153–0.974; P = 0.045) were found to be independent factors associated with uncontrolled blood pressure.ConclusionsThe result showed that non-adherence to antihypertension drugs is associated with uncontrolled blood pressure. Then, age could be associated with uncontrolled blood pressure. Thus, pharmacists and other healthcare providers should pay attention to improving medication adherence and maintaining the controlled blood pressure.

Serosurvey of anti-Toxocara antibodies and risk factors in adolescent and adult pregnant women of southeastern Brazil.

Toxocariasis is worldwide endemic parasitic anthropozoonosis with high risk to those in in vulnerable populations and particularly during pregnancy and childhood. Although the prevalence of anti-Toxocara spp. antibodies has been extensively studied, risk factors of pregnant women of different ages remains to be established. This study was designed to i) assess the presence of anti-Toxocara spp. antibodies in pregnant women that presented to the public health system in a city of southeastern Brazil, and ii) determine the risk factors for toxocariasis in adolescent and adult pregnant women. This cross-sectional study included 280 pregnant women (71 aged up to and including 17 years [adolescents] and 209 aged 18 years and older [adults]). Pregnant women voluntarily agreed to complete a socioeconomic questionnaire and provide serum samples. Anti-Toxocara IgG antibodies were screened by Enzyme-Linked Immunosorbent Assay (ELISA). Univariable and multivariable logistic regression models were performed to assess the risks for toxocariasis. Overall, 20.7% of pregnant women were seropositive (33.8% of adolescents and 16.3% of adults). Prevalence in pregnant adolescents was 2.6-fold higher than in adults (Odds ration [OR]: 2.63; 95% CI: 1.42–4.86, p = 0.003). Multivariate analysis revealed that contact with soil (p = 0.01; OR = 4.76) and being in the first trimester of pregnancy (p = 0.03; OR = 0.17) had significantly greater risk of toxocariasis for adolescents, and attainment of elementary through middle school education level (p = 0.05; OR = 8.33) was a risk factor in adult pregnant women. Toxocariasis is likely underreported and neglected in adolescent pregnant women; this age group should always be monitored for toxocariasis and correspondent clinical signs, particularly at late pregnancy.

Prevalence and associated factors of psychological distress in tuberculosis patients in Northeast China: a cross-sectional study

BackgroundPsychological distress, a major comorbidities of tuberculosis (TB) patients, has posed a serious threat to the progress being made in global TB programs by affecting treatment adherence and health outcomes. However, the magnitude and associated factors of psychological distress have not been fully studied in China. The aim of the current study was to assess the prevalence of psychological distress in TB patients and to further determine the effects of socio-demographic characteristics, health-related variables, substance use status, social support, and experienced stigma on psychological distress.MethodsA cross-sectional survey was conducted among TB patients attending three medical institutions in Dalian, Liaoning Province, Northeast China from November 2020 to March 2021. A structured questionnaire was developed to collect data on patients’ socio-demographic characteristics, health-related information, substance use status, psychological distress, family function, doctor-patient relationship, policy support, experienced stigma and so on. The binary logistics regression model was used to determine the associated factors of psychological distress.ResultsA total of 473 TB patients were enrolled in this study, and the prevalence of psychological distress was 64.1%. Binary logistic regression analysis revealed that patients with a middle school education level or above (OR: 0.521, 95%CI: 0.279–0.974), no adverse drug reactions (OR: 0.476, 95%CI: 0.268–0.846), and regular physical exercise (OR: 0.528, 95%CI: 0.281–0.993) were more likely to stay away from psychological distress. However, patients who had a high economic burden (OR: 1.697, 95%CI: 1.014–2.840), diabetes (OR: 2.165, 95%CI: 1.025–4.573), self-rated illness severe (OR: 3.169, 95%CI: 1.081–9.285), perceived poor resistance (OR: 2.065, 95%CI: 1.118–3.815), severe family dysfunction (OR: 4.001, 95%CI: 1.158–13.823), perceived need for strengthen psychological counseling (OR: 4.837, 95%CI: 2.833–8.258), and a high experienced stigma (OR: 3.253, 95%CI: 1.966–5.384) tended to have a psychological distress.ConclusionsThe study found that the proportion of psychological distress among TB patients was high in Northeast China, and it was influenced by a variety of factors. Effective interventions to reduce psychological distress in TB patients urgently need to be developed, and greater attention should be given to patients with risk factors.

Factors associated with dual use of waterpipe tobacco and cigarettes among adults in Pakistan

Little is known about dual use of waterpipe tobacco and cigarettes, especially in countries where both are prevalent. This study aimed to assess demographic correlates, patterns of use and quit behaviours of waterpipe users in Pakistan who also smoke cigarettes. Data were taken from a randomized controlled trial in Pakistan that assessed smoking cessation in 510 adult waterpipe users, stratified on concurrent cigarette use. Logistic regression analysis was done to assess the association between waterpipe tobacco users who also smoke cigarettes (dual use) and their demographic characteristics, smoking history and quit behaviour. Unadjusted odds ratios (OR) and adjusted OR (ORa) and 95% confidence intervals (CI) were determined. Dual use was significantly associated with younger age (ORa = 0.36, 95% CI: 0.19-0.70) and middle-school educational level (11-15 years), versus no formal education, (ORa = 2.01, 95% CI: 1.15-3.50). Dual use was also associated with smoking less than all day versus all day (defined as continuously for several hours) (ORa = 2.71, 95%: CI 1.73-4.25) and younger age at starting smoking (ORa = 0.95, 95% CI: 0.93-0.98). No association was found between dual use and sex, marital status, duration of smoking, nicotine dependence or quit history. Waterpipe tobacco users who also smoke cigarettes differ from waterpipe-only users, particularly in demographic characteristics. More research is needed to explore the interaction between these two smoking behaviours. Health promotion and cessation interventions in Pakistan should consider tailoring their approach to account for the unique characteristics of dual waterpipe and cigarette users.

Prevalence and Risk Factors for Anemia in Non-pregnant Childbearing Women from the Chinese Fifth National Health and Nutrition Survey

Anemia is a public health issue for developing countries, especially for women of childbearing age. The aim of this study was to assess the anemia status and analyze the risk factors for anemia in Chinese childbearing women aged 18–49 years. Hemoglobin concentration was measured by the HiCN method in the Fifth Chinese National Nutrition and Health Survey (CNNHS) in 2010–2012. Age, region type, ethnicity, bodyweight, height, education, season and smoke habit were recorded in unified questionnaires. Latitude was divided by China’s Qinling Mountains and Huaihe River. Childbearing women (28,289) from the CNNHS 2010–2012 were included in this study. The median hemoglobin concentration was 136.2(126.6–145.0) g/L, and it was significantly higher than in CNNHS 2002 (132.5 (122.3–141.6) g/L). The prevalence of anemia was 15.0%, and it was significantly lower than 10 years ago. The logistic regression analysis showed anemia in Chinese childbearing women was specifically related to 30–39 age group (P = 0.004), in spring (P < 0.0001) or in winter (P = 0.006), small and medium-sized cities (P = 0.044) and middle school education level (P = 0.027). The results showed that anemia status among childbearing women was greatly improved over 10 years since 2002, but it was still more severe than the rest of the populations. The nutrition propaganda and education is recommended for childbearing women to help them to improve the nutritional status on their own.

Analysis of 124 Suicide Cases in Wuhua District in Kunming

To analyze the relationship between the suicide method and the sex, age, education background and cause of suicide to provide reference for the forensic identification of suicide. After scene investigation, external body examination, autopsy and case investigation, 124 identified suicide cases which happened in recent three years in Wuhua district in Kunming were collected. Analytical methods as chi-square test and descriptive statistics were performed by SPSS 22.0. In all the suicide cases, male to female ratio was 1.53∶1. The suicide methods were mainly fatal fall, hanging and drowning. The ratio of local to non-native residents was 1∶1. The suicide rate in the people with primary school or junior middle school education level was highest. The group of >10-50 years tended to choose fatal fall suicide and people over 60 years were more likely to choose hanging. People with different academic background tended to choose fatal fall suicide. The suicide methods as fatal fall and hanging were chosen because of mental and physical diseases and economic problems, while the suicides with emotional problems were more likely to choose fatal fall and poisoning. Suicide belongs to a kind of complex cases. For the cases of suspected suicide, complete exploration and overall consideration should be done to determine the nature of cases based on comprehensive analysis of all the influence factors.

Correlation between self-reported gingival bleeding and type 2 diabetes mellitus in aged ≥18 years adults in China

Objective: To understand the correlation between self-reported gingival bleeding and type 2 diabetes mellitus (T2DM) in adults in China. Methods: The database of China' s 2010 Chronic Disease and Risk Factor Surveillance (CCDRFS) survey among people aged ≥18 years was used to analyze the demographic characteristics of subjects with self-reporting gingival bleeding and the prevalence of major chronic diseases among adults. Correlation and interaction analyses were conducted on the relationships between frequent gingival bleeding and T2DM, hypertension and dyslipidemia, and interaction of age and gingival bleeding, age and hypertension, age and dyslipidemia, age and gender on the prevalence of T2DM. Results: Among 93 647 adults surveyed, 87.4% were in Han ethnic group. The incidence of frequent gingival bleeding was higher in females (63.6%) than in males (36.4%). The incidence of frequent gingival bleeding was highest (30.1%) in adults with middle school education level. Among the adults aged 45-60 years, 12.8%(2 839/22 179) had T2MD but no gingival bleeding, 15.6% (163/1 044) had both frequent gingival bleeding and T2DM, frequent gingival bleeding was correlated with T2DM (OR=1.29, 95%CI: 1.08-1.54) and the interaction with age had influence on T2DM (P<0.005). In males, frequent gingival bleeding was correlated with T2DM (OR=1.30, 95% CI: 1.08-1.56, P=0.005). In hypertension group, frequent gingival bleeding was correlated with T2DM (OR=1.25, 95% CI: 1.07-1.46), and interaction of hypertension and gingival bleeding had influence on T2DM (P<0.05). Conclusions: The positive correlation between frequent gingival bleeding and T2DM was observed in adults surveyed, and the interaction of age and hypertension had influence on prevalence of T2DM. Frequent gingival bleeding was correlated with T2DM in males either.

Risk factors of Schistosoma japonicum infection in Xingzi County

To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County, Jiangxi Province. Six administrative villages from different areas were randomly selected by the cluster sampling method as the study sites in Xingzi Country in 2013, and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato-Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi-square test analysis and multivariate Logistic regression model. In 2013, there were 2 050 residents received the stool examination and 146 persons were positive, the schistosome infection rate was 7.1%. The Chi-square test showed that gender, age, occupation and education level were associated with the population infection rate (χ2 = 26.485、16.836、25.700、 90.805, all P < 0.05). The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female; the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed; the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed; the probability of schistosomiasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed; the probability of infection of fishermen was the highest, which was 3.053 times as much as that for the other professional crowds. The risk factors of schistosome infection mainly include gender, occupation and the education level. We should strengthen the health education of schistosomiasis control, protection against the infested water contact, and so on.

Cross-section survey on smoking behavior and cognition in Chongqing, 2014

To investigate the prevalence of smoking, smoking cessation, passive smoking and awareness of the dangers of tobacco in population in Chongqing and provide evidence for developing prevention and control measures. A total of 5 400 residents aged ≥18 years were selected from 9 districts/counties in Chongqing through stratified multi-stage cluster sampling and face-to-face interviews were conducted among them. Indicators as current smoking rates, smoking cessation rates and passive smoking rates were calculated by the weight of age proportions from 2010 population census. The analytical method was based on complex sampling design. The current smoking rate of the residents aged ≥18 years was 27.4% (male: 53.5% and female: 1.1%), which was highest in age group 40-50 years (58.4%) for males. The current smoking rate among rural residents was higher than that in urban residents. The prevalence of daily cigarette smoking was 27.5%, which was significantly higher in southeastern Chongqing. The rate of passive smoking was 52.4%. Among daily smokers, the mean number of cigarettes smoked was 17.5 per day (men: 17.6 per day; women: 13.5 per day). The daily smoked cigarette number in males was higher in age group 40-50 years (20.1 per day) and those with junior middle school education level (18.9 per day). The proportion of the current smokers who smoked more than 20 cigarettes per day (the rate of heavy smoker) was higher in males than in females and in rural residents than in urban residents. The proportion of heavy smokers was 59.3%, which was highest in age group 40-50 years (66.8%), followed by those with junior middle school educational level (65.2%). The average age of smokers when they stared to smoke was 20.8 years old, which was low in males and rural residents. About 80.2% of the smokers stared to smoke under 25 years old, and 70.3% of the smokers stared to smoke between 15 and 25 years old. The overall rate of smoking cessation was 20.1% and the successful smoking cessation rate was 13.7%. The two rates increased with age, the successful smoking cessation rate was lowest in age group 18-40 years (4.8%). The awareness of the tobacco risk related knowledge seemed poor among the residents, only 19.6% of the residents were aware that smoking could cause serious diseases (stoke, heart disease and lung cancer). 21.9% of the residents were aware that passive smoking could cause serious diseases (heart disease, lung disease and lung cancer). Current prevalence of smoking in males in Chongqing remains at a high level, indicating that the publicity programs on the tobacco risk related knowledge needs to be strengthened and the tobacco control needs more efforts. The tobacco control in Chongqing is still facing serious challenge.

Yalova İlindeki Süt Sığırcılığı İşletmelerinin Yapısal Özelliklerini Etkileyen Faktörler: Yetiştirme Faaliyetlerinin Belirlenmesi

This research has been performed to determine dairy farms’ breeders’ social conditions, presence of animals, care, milk production, happiness with animal farming, problems and situation of being organized in Yalova. The data that obtained from 324 randomly chosen dairy farms around the city by the means of the survey comprised the material of research. The obtained data has been analyzed in SPSS package program by taking animal numbers, age and educational background of breeders as factors affecting the structural condition of farm. In the analysis of race distribution it was determined that breeders having primary education preferred to use crossbred animals, whereas breeders having secondary, high school and higher education tended to use culture breeds. For determining the heat in animals, breeders who have primary school education take bellowing and mounting of animals into consideration. All breeders at any education level considered the 15-18 months of age as age at fist insemination for heifers. As the age of breeders increased, contrary to education level, the ratio for 15-18 month age criterion decreased. In the farms producing less than 10 kg milk the ratio of farmers having primary school education is 68.9%. This ratio is 8.5% for high school and higher graduates. 61.2% of breeders who have middle school education level obtain 11-20 kg milk yield in their farms. While 48.6% of breeders who have less than 5 animals obtain 10 kg milk yield, as the number of animals rises, this rate declined to 23.1%. In the farms having less than 5 animals the proportion of obtaining 10-21 kg milk yield is 48.4%. As the animals numbers increased this proportion increased up to 63.5%

Oral health of a Brazilian population on renal dialysis

The purpose of this study was to assess the oral health of patients with chronic renal failure (CRF) undergoing hemodialysis in Brazil. A dentist examined 160 subjects aged 40 to 85 years of age. Data was collected on dental caries, use of and need for dentures, oral mucosa, periodontal disease and temporomandibular joint status. All subjects were interviewed about their socioeconomic status, dental and medical history, and oral hygiene habits. Most subjects had hypertension (49.4%); used the public service for their medical care (69.4%); had a middle school educational level (83.1%); and did not complain of xerostomia (60.0%). The majority used private oral healthcare services and used a toothbrush only for oral hygiene. The mean DMFT was 26.0 (standard deviation 7.7). Most individuals did not wear dentures, but needed some type of prosthesis. Lesions of the oral mucosa (3.1%), signs (2.5%) and symptoms (3.8%) of temporomandibular dysfunction could be observed in only a few patients. The oral health of the subjects examined was poor. These persons needed their oral condition monitored by a dentist and their oral disease treated as well as receiving instruction on oral hygiene.

Reliability of the information about the history of diagnosis and treatment of hypertension. Differences in regard to sex, age, and educational level. The Pró-Saúde study.

To assess the intraobserver reliability of the information about the history of diagnosis and treatment of hypertension. A multidimensional health questionnaire, which was filled out by the interviewees, was applied twice with an interval of 2 weeks, in July '99, to 192 employees of the University of the State of Rio de Janeiro (UERJ), stratified by sex, age, and educational level. The intraobserver reliability of the answers provided was estimated by the kappa statistic and by the coefficient of intraclass correlation (CICC). The general kappa (k) statistic was 0.75 (95% CI=0.73-0.77). Reliability was higher among females (k=0.88, 95% CI=0.85-0.91) than among males (k=0.62, 95% CI=0.59-0.65). The reliability was higher among individuals 40 years of age or older (k=0.79; 95% CI=0.73-0.84) than those from 18 to 39 years (k=0.52; 95% CI=0.45-0.57). Finally, the kappa statistic was higher among individuals with a university educational level (k=0.86; 95% CI=0.81-0.91) than among those with high school educational level (k=0.61; 95% CI=0.53-0.70) or those with middle school educational level (k=0.68; 95% CI=0.64-0.72). The coefficient of intraclass correlation estimated by the intraobserver agreement in regard to age at the time of the diagnosis of hypertension was 0.74. A perfect agreement between the 2 answers (k=1.00) was observed for 22 interviewees who reported prior prescription of antihypertensive medication. In the population studied, estimates of the reliability of the history of medical diagnosis of hypertension and its treatment ranged from substantial to almost perfect reliability.
