Relationship between lifestyle factors and hyperhomocysteinemia in general Chinese population: a cross-sectional study

Objectives: Hyperhomocysteinemia (Hhcy) is a known cardiovascular disease (CVD) risk factor. Observational studies had supported the role of lifestyle factors such as physical activity, diet and alcohol consumption in CVD prevention. Our study aimed to determine the relationship between Hhcy and lifestyle factors in general Chinese population.

Methods: In this cross-sectional study, a total of 7135 adults (3320 men and 3815 women) aged 35 years or older were recruited from the rural Northeast China. Data on lifestyle factors, such as physical activities, sleep duration, current smoking and drinking status, dietary habits and familial factors were collected in interviews and laboratory examinations were performed by well-trained personnel.

Results: Plasma total homocysteine (tHcy) level was higher in men than in women, and greater in the elderly than in other age groups. Subjects with Hhcy were more likely to be current smokers (men: OR 1.328, 95% CI 1.143–1.543, p<0.001; women: OR 1.465, 95% CI 1.214–1.767, p<0.001). Separately, men with Hhcy were more likely to have an education of primary school or below (OR 1.251, 95% CI 1.068–1.465, p=0.006) and less likely to eat more vegetables (OR 0.927, 95% CI 0.863–0.996, p=0.037) than the normal-tHcy participants. In women, participants with Hhcy were more likely to have longer sleeping time (>9h/d) (OR 1.677, 95% CI 1.292–2.177, p<0.001), low physical activity (OR 1.721, 95% CI 1.197–2.475, p=0.044) and increased diet score (OR 1.126, 95% CI 1.007–1.259, p=0.037) and less likely to be current drinkers (OR 0.488, 95% CI 0.297–0.802, p=0.005) than the normal-tHcy participants.

Conclusion: Our study revealed that physical activity and current drinking status were not significantly associated with Hhcy in males, but inversely associated in females. In both genders, current smoking status and dietary habits were significantly associated with Hhcy. Our study supports existing recommendations for Chinese to maintain a physically active behaviors and healthy lifestyle habits.     

Awareness of hypertension and depressive symptoms: a cross-sectional study in a primary care population

Objective: To investigate the association of hypertension awareness and depressive symptoms, and to analyse factors predisposing aware hypertensives to depressive symptoms.

Design: Cross-sectional study in a primary care population.

Setting: Cardiovascular risk factor survey in two semi-rural towns in Finland.

Subjects: Two thousand six hundred seventy-six middle-aged risk persons without an established cardiovascular or renal disease or type 2 diabetes.

Main outcome measures: Depressive symptoms, previous and new diagnosis of hypertension.

Results: Hypertension was diagnosed in 47.9% of the subjects, of whom 34.5% (442/1 282) had previously undetected hypertension. Depressive symptoms were reported by 14% of the subjects previously aware of their hypertension, and by 9% of both unaware hypertensives and normotensive subjects. In the logistic regression analysis, both the normotensive (OR 0.62, 95% CI 0.45–0.86) (p?=?0.0038) and the unaware hypertensive subjects (OR 0.54, 95% CI 0.35–0.84) (p?=?0.0067) had lower risk for depressive symptoms than the previously diagnosed hypertensives. Among these aware hypertensives, female gender (OR 3.61, 95% CI 2.06–6.32), harmful alcohol use (OR 2.55, 95% CI 1.40–4.64) and obesity (OR 2.50, 95% CI 1.01–6.21) predicted depressive symptoms. Non-smoking (OR 0.57, 95% Cl 0.33–0.99) and moderate leisure-time physical activity compared to low (OR 0.53, 95% CI 0.33–0.84) seemed to buffer against depressive symptoms.

Conclusion: Depressive symptoms are common in hypertensive persons even without comorbidities, if the person is already aware of his/her hypertension. Many modifiable, lifestyle associated factors may contribute to the association of hypertension and depressive symptoms.

• Key Points

• Hypertension and depressive symptoms are known to form a toxic combination contributing even to all-cause mortality.

• Comorbidities or the labelling effect of the diagnosis of hypertension can confound their association.

• Our study shows that depressive symptoms are common in hypertensive persons even without comorbidities, if the person is already aware of his/her hypertension.

• Many modifiable, lifestyle-associated factors may contribute to the association of hypertension and depressive symptoms.

• When treating hypertensive patients, consideration of depressive symptoms is important in order to promote favorable lifestyle and control of hypertension.

     

Frequent attenders in general practice and immigrant status in Norway: A nationwide cross-sectional study

Objective. To compare the likelihood of being a frequent attender (FA) to general practice among native Norwegians and immigrants, and to study socioeconomic and morbidity factors associated with being a FA for natives and immigrants. Design, setting and subjects. Linked register data for all inhabitants in Norway with at least one visit to the general practitioner (GP) in 2008 (2 967 933 persons). Immigrants were grouped according to their country of origin into low- (LIC), middle- (MIC), and high-income countries (HIC). FAs were defined as patients whose attendance rate ranked in the top 10% (cut-off point > 7 visits). Main outcome measures. FAs were compared with other GP users by means of multivariate binary logistic analyses adjusting for socioeconomic and morbidity factors. Results. Among GP users during the daytime, immigrants had a higher likelihood of being a FA compared with natives (OR (95% CI): 1.13 (1.09–1.17) and 1.15 (1.12–1.18) for HIC, 1.84 (1.78–1.89) and 1.66 (1.63–1.70) for MIC, and 1.77 (1.67–1.89) and 1.65 (1.57–1.74) for LIC for men and women respectively). Pregnancy, middle income earned in Norway, and having cardiologic and psychiatric problems were the main factors associated with being a FA. Among immigrants, labour immigrants and the elderly used GPs less often, while refugees were overrepresented among FAs. Psychiatric, gastroenterological, endocrine, and non-specific drug morbidity were relatively more prevalent among immigrant FA compared with natives. Conclusion. Although immigrants account for a small percentage of all FAs, GPs and policy-makers should be aware of differences in socioeconomic and morbidity profiles to provide equality of health care.Key Words: Emigrants and immigrants, general practice, health care research, morbidity, Norway, primary health care, registries, socioeconomic factors

• Immigrants are a heterogeneous growing group in Europe and they seem to use primary care differently than natives.
• Immigrants more often become frequent attenders, especially those coming from middle- and low-income countries.
• However, elderly immigrants are underrepresented among frequent attenders in general practice.
• Gastrological, endocrine, and non-specific morbidity are relatively more prevalent among immigrant frequent attenders compared with natives.

     

Correlates of low back pain in a general population sample: a multidisciplinary perspective

This study identifies correlates of low back pain in a general population sample and defines a profile of subjects with low back pain. A multidisciplinary approach was employed that required surveying and physically assessing 674 subjects on 105 variables in biographical, anatomical, strength and flexibility measurement categories. No attempt was made to select subjects from specific occupational, age, athletic, psychological and anatomical groups or subjects with specific biographical features, which may have resulted in a sample that was atypical of the general population. The results of this study based on a causal comparative ex post facto research design corroborated selected findings of previous research conducted on nongeneral population samples. These findings include relationships between low back pain and age, body type, sex, stress, smoking, selected types of physical activity, occupation and previous injuries to the neck, shoulders, back and upper legs, as well as previous episodes of low back pain. Additional correlates of low back pain that were identified and have little or controversial review in the back literature include: delayed low back pain syndrome caused by abrupt changes in running frequency, Q angle, pes cavus, leg length (right and left), trunk length, genu recurvatum and multiplane strength and flexibility limitations in the hip joints.     

Mental health treatment dropout and its correlates in a general population sample

BACKGROUND: Dropping out of mental health treatment prematurely may affect treatment outcome. However, we have limited knowledge about the epidemiology of mental health treatment dropout. The objectives of this analysis were to estimate the rates of dropout in individuals who had received mental health treatment provided by different health professionals and to identify factors associated with mental health treatment dropout. METHODS: Data from the Canadian Community Health Survey-Mental Health-Well-being were used. Participants who had used mental health services in the past 12 months were included in the analysis (n=3556). The percentages dropping out of mental health treatment provided by various health professionals were estimated. Logistic regression was used to identify factors associated with treatment dropout. RESULTS: The overall rate of dropout from mental health treatment in the past 12 months was 22.3%. Participants who had used services provided by family doctors/general practitioners had the lowest rate of dropout (11.8%). The dropout rate was 22.7% in those who were treated by psychiatrists and was 21.9% in participants who had seen psychologists. Young (15-25 years), nonwhite and individuals who reported having had a mood disorder or having had substance dependence were more likely to terminate treatment prematurely. CONCLUSIONS: In Canada, a large percentage of individuals who use mental health services prematurely terminate their treatment. Clinical factors may play important roles in treatment dropout. Patients with substance dependence and those with mood disorders have a high risk of treatment dropout.     

Pain catastrophizing and general health status in a large Dutch community sample

The aim of the present study was to examine the association between pain catastrophizing and general health status in a Dutch adult community sample, including various subgroups of people with musculoskeletal pain in the analyses. For exploratory reasons this study partly replicated previous studies of the factor structure, reliability, and validity of the Pain Catastrophizing Scale (PCS). Results demonstrated that across different pain subgroups, catastrophizing uniquely contributed variance to the prediction of the various aspects of general health status beyond the variance explained by pain intensity, age, gender, and chronicity. Across subgroups strongest associations were found between catastrophizing and mental health, general health perception, social functioning, and vitality. Furthermore, the association between catastrophizing and the various aspects of general health status was not moderated by the chronicity of the pain. Results of the confirmatory factor analysis statistically confirmed a three-factor model of the PCS, which was invariant across different subgroups of people with musculoskeletal pain. Inter-factor correlations were high, and the incremental explanatory power of the three-factor model over that of a one-factor model was only marginal. This implies that a one-factor model might be justifiable as well, at least in the general community. Across various pain subgroups the reliability of the PCS total and subscales was adequate. Additional evidence for the concurrent validity of the PCS was found as well.     

Serum sialic acid in a random sample of the general population.

BACKGROUND: The serum sialic acid (SA) concentration has been reported to be a potentially useful but nonspecific disease marker. We wanted to study which factors influence SA concentration in a well-characterized healthy population. METHODS: SA was determined in 97 women and 96 men with a colorimetric Warren method. RESULTS: The mean +/- SD concentrations of SA were 634 +/- 109 (95% confidence interval, 612-656) and 630 +/- 106 (95% confidence interval, 608-651) mg/L for women and men, respectively. The serum SA showed a significant positive association with body mass index and with systolic and diastolic blood pressure among both women and men. SA also correlated significantly with the use of contraceptive pills and age among women and with smoking among men. CONCLUSIONS: Our study suggests that SA does not increase with age in men but appears to increase with female menopause. The strong positive association with blood pressure may explain why SA predicts cardiovascular mortality.     

The influence of maternal vulnerability and parenting stress on chronic pain in adolescents in a general population sample: The TRAILS study

Investigating possible psychosocial predictors of unexplained chronic pain in adolescents is crucial in understanding its development and prevention. A general population sample of adolescents (n = 2230) from the TRAILS cohort study was investigated longitudinally to assess the influence of maternal vulnerability, in terms of anxiety, depression and stress, and parenting stress at age 10–12 years, on the presence of chronic pain at age 12–15 years. Of these adolescents, 269 (12.9%) reported experiencing chronic pain, of which 77% reported severe chronic pain and 22% reported multiple chronic pain. Maternal anxiety, maternal stress and higher levels of parenting stress were related to chronic pain at a later age. Subgroup analyses showed similar results for adolescents with severe chronic pain. Mediation analyses indicated that parenting stress mediates the effect between maternal anxiety, or stress, and chronic pain. The findings suggest that interventions to diminish maternal feelings of anxiety and stress, while in turn adjusting maternal behaviour, may prevent the development of chronic pain in adolescence.     

Methodology and quality control in EPIGRAM, a pharmacoepidemiological study of obesity in general practice

The EPIGRAM pharmacoepidemiological study was conducted in general practitioners prescribing orlistat (Xenical) in order to describe, under real clinical conditions, the management of obese or overweight patients. A 1-year follow-up of a patient cohort treated with orlistat was also conducted. Quality criteria specific to the study were defined to ensure the scientific validity of the results; these criteria mainly involved the following items: independent scientific committee, sampling investigator's recruitment, study organisation and quality control of the collected data. On-site control visits of a sample of 13% of participating GPs revealed that 75% of the controlled data were documented in a source file of which 85% were consistent with the source data. Only 1% of the 130 000 controlled data (data were controlled only on visits for which information was available) gave rise to correction requests. Of the patients treated with orlistat on inclusion, 17% were lost to follow-up by their GP and 25% were contacted directly at the end of the study.     

Social disparities in diabetes care: a general population study in Denmark

Objective: We investigated the association between socioeconomic factors and the attainment of treatment goals and pharmacotherapy in patients with type 2 diabetes in Denmark.

Design: A cross-sectional population study.

Setting: The municipality of Naestved, Denmark.

Subjects: We studied 907 patients with type 2 diabetes identified from a random sample of 21,205 Danish citizens.

Main outcome measures: The proportion of patients who were not achieving goals for diabetes care based on their HbA_1c, LDL-cholesterol, blood pressure, and lifestyle, and the proportion of patients who were treated with antihypertensive and cholesterol- and glucose-lowering medication.

Methods: We investigated the association of the socioeconomic factors such as age, gender, education, occupation, income, and civil status and attainment of treatment goals and pharmacotherapy in logistic regression analyses. We investigated effect modification of cardiovascular disease and kidney disease.

Results: Middle age (40–65 years), low education level (i.e. basic schooling), and low household income (i.e. less than 21,400 € per year) were associated with nonattainment of goals for diabetes care. The association of socioeconomic factors with attainment of individual treatment goals varied. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Socioeconomic factors were not associated with treatment goals for hyperglycemia. Socioeconomic factors were inconsistently associated with pharmacotherapy. There was no difference in contacts to general practitioners according to SES.

Conclusions: In a country with free access to health care, the socioeconomic factors such as middle age, low education, and low income were associated with nonattainment of goals for diabetes care.

• KEY POINTS

• Middle age, low education, and low income were associated with nonattainment of goals for diabetes care, especially for lifestyle goals.

• Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure.

• Association of socioeconomic factors with pharmacotherapy was inconsistent.

     

Comorbidity of obesity and pain in a general population: results from the Southern Pain Prevalence Study.

This cross-sectional study examines the relation between obesity and self-reported pain (moderate or severe pain occurring at least monthly) in a general population sample of adults in the southeastern United States (N = 3637). Results of the study suggest that obese adults (body mass index [BMI] >30) are more likely to experience pain than their normal-weight and underweight counterparts. Respondents classified as class I obese (BMI of 30 to 34.9) were 1.762 times as likely as the underweight and normal weight participants to report severe pain. Class II obese respondents (BMI of 35 to 39.9) were 1.888 times as likely to experience severe pain. Those respondents categorized as class III obese were most likely to report severe pain--2.297 times as likely as the underweight and normal-weight respondents. Analyses demonstrated a similar trend for respondents reporting moderate to severe pain. Adults who are obese are also more likely to report experiencing pain in multiple locations. This study complements clinical research that links pain and obesity and extends it into a general population. Because this is a cross-sectional study, further research is needed to discern causal explanations for the relation between self-reported pain and obesity. PERSPECTIVE: This article provides a population-level depiction of the positive relation between obesity and self-reported pain, which complements clinical research on the topic. It may prompt future research to shape interventions and treatment for both pain and obesity.     

Burnout syndrome in surgical oncology and general surgery nurses: A cross-sectional study

Purpose

The occurrence of burnout syndrome is strongly associated with and modulated by multiple personality and environmental factors. In Poland, nurses experience a discrepancy between the demands, expectations and social status of the position of their profession and low salaries. Such a situation provokes frustration and depression, and further leads to problems of adaptation including burnout syndrome. The aim of this study was to evaluate the occurrence of burnout syndrome among nurses working in general surgery and surgical oncology specialties.

Methods

The study was designed as a cross-sectional questionnaire survey. It was undertaken in the largest Hospital in the Pomeranian region of Poland. The participants included 60 nurses working in two departments: General Surgery and Surgical Oncology. The study was based upon an anonymous self-test composed of a questionnaire and three psychological measures: Maslach Burnout Inventory (MBI), Psychological Burden Scale and a self-constructed questionnaire on job satisfaction.

Results

Intensity of burnout syndrome was significantly higher among oncology nurses than among surgical ones. There was also a strong but not significant trend towards higher Psychological Burden Scale in the group of oncology nurses.

Conclusions

The study revealed a high degree of emotional burden and burnout in nurses working in the study hospital suggesting that nurses are at great occupational risk. The findings of the study provide evidence of the potential need to restructure the system and suggest that nurses need more control of their work including a higher degree of involvement in clinical decision-making.     

Differences in health status of older people aged 65 and above after total hip replacement compared with the normal population: a cross-sectional study

Aim. The aim of the study was to describe the health status of older patients with osteoarthrosis following total hip replacement and to compare their health status with population norms in order to analyse the need for a rehabilitation programme after total hip replacement. Background. Total hip replacement is a very efficient operation in terms of pain relief and improvement of walking ability. However, after the operation some patients still report low health status. Method. A cross‐sectional study including 287 older patients aged 65–74 and 75+ years who had had total hip replacement within the previous 12 months was performed. Patients from five Danish counties received a mailed questionnaire requesting information about their health status and demographic data. The Short‐Form 36 measures eight domains of importance of health. The scores related to each dimension are transformed to an interval scale ranging from 0 (worst score) to 100 (best score). Danish population norm data were used as reference point. Results. In total, 287 (91.4%) patients responded. The patients completed the questionnaire 207 (114) days after surgery within a range of 10–360 days. In all eight health domains patients reported significantly lower scores than the age specific norm population. Conclusion. Our results indicate that health status is scored lower for patients after total hip replacement. This implies that there might be a need for further postoperative rehabilitation based on the identification of problems experienced by patients in the postoperative period. Relevance to clinical practice. Patients health status is a predictor for well‐being, quality of life and survival. Older people need rehabilitation after surgery to reduce dysfunction and improve perception of health. Our results demonstrate a need for further studies examining problems experienced by patients in the postoperative period. Intervention research is needed before such a programme can be implemented.
