Low back pain and depression: a study in a population of Mexican workers

The objective of this study was to analyze whether lumbar spondyloarthrosis is associated with depression. A cross-sectional comparative survey was conducted, in which 99 workers insured by the Mexican Social Security Institute (IMSS, according to its designation in Spanish), ranging from 23-55 years of age, participated. Conditional logistic regression analysis showed that chronic lumbar spondyloarthrosis illness, when adjusted for participation in sports activity, was found to be associated with depression (OR = 3.4; CI 95% 1.2-9.4). This suggests that among those suffering said physical condition there is greater association with depressive symptoms. The study's results indicate the necessity of evaluating all workers with lumbar spondyloarthrosis for the presence of depression, and the suggestion is made that psychological support treatment be implemented in conjunction with physical treatment as a means of preventing depression.     

Depression and elder abuse and neglect among a community-dwelling Chinese elderly population

Our recent survey of an elderly cohort in mainland China suggests that elder abuse and neglect are common. Unfortunately, there is minimal knowledge about the risk factors for elder abuse and neglect among this population. We aimed to examine depression as a risk factor for elder abuse and neglect among Chinese elderly. A cross-sectional study was performed in a major urban medical center in NanJing, China. Depression was assessed using the Geriatric Depression Scale and direct questions were asked regarding abuse and neglect experienced by the elderly since the age of 60; 412 patients completed the survey. The mean age of the participants was 70 and 34% were female. Depression was found in 12% of the participants and elder abuse and neglect was found in 35% of the participants. After multiple logistical regression, feeling of dissatisfaction with life (OR, 2.92; 95% CI, 1.51-5.68, p < 0.001), often being bored (OR, 2.91; CI, 1.53-5.55, p < 0.001), often feeling helpless (OR, 2.79; CI, 1.35-5.76, p < 0.001), and feeling worthless (OR, 2.16; CI, 1.10-4.22, p < 0.001) were associated with increased risk of elder abuse and neglect. Multiple logistic regression modeling showed that depression is independently associated with elder abuse and neglect (OR, 3.26; CI, 1.49-7.10, p < 0.003). These findings suggest that depression is a significant risk factor associated with elder abuse and neglect among Chinese elderly.     

Does team lifting increase the variability in peak lumbar compression in ironworkers?

Ironworkers frequently perform heavy lifting tasks in teams of two or four workers. Team lifting could potentially lead to a higher variation in peak lumbar compression forces than lifts performed by one worker, resulting in higher maximal peak lumbar compression forces. This study compared single-worker lifts (25-kg, iron bar) to two-worker lifts (50-kg, two iron bars) and to four-worker lifts (100-kg, iron lattice). Inverse dynamics was used to calculate peak lumbar compression forces. To assess the variability in peak lumbar loading, all three lifting tasks were performed six times. Results showed that the variability in peak lumbar loading was somewhat higher in the team lifts compared to the single-worker lifts. However, despite this increased variability, team lifts did not result in larger maximum peak lumbar compression forces. Therefore, it was concluded that, from a biomechanical point of view, team lifting does not result in an additional risk for low back complaints in ironworkers.     

Declining negative consequences related to alcohol misuse among students exposed to a social norms marketing intervention on a college campus

OBJECTIVE: The authors examined whether alcohol-related negative consequences decreased among students exposed to an intervention. PARTICIPANTS: Beginning in 1999, approximately 2,500 randomly selected undergraduates from a 4-year US university annually participated in a Web-based survey over 6 years. METHODS: The educational intervention used social norms initiatives. Main outcome measures included recall of intervention, estimated blood alcohol content (eBAC) when drinking, and 10 negative consequences from alcohol within the past year. RESULTS: First-year students recalling exposure had lower odds of negative consequences (odds ratio [OR] = 0.78, 95% confidence interval [CI] = 0.64-0.95) and of having an eBAC higher than .08 (OR = 0.76, 95% CI = 0.62-0.92). Over the 6 study years, the odds among all participants of experiencing (a) none of 10 alcohol consequences nearly doubled (OR = 2.13, 95% CI = 1.82-2.49) and (b) multiple consequences decreased by more than half (OR = 0.43, 95% CI = 0.36-0.50). CONCLUSIONS: These findings have important implications for US colleges and universities engaged in the reduction of harm associated with alcohol misuse.     

Effects of beverage-specific alcohol consumption on drinking behaviors among urban youth

Alcoholic beverage consumption among high school students has shifted from beer to liquor. The current longitudinal study examined the effects of beverage-specific alcohol use on drinking behaviors among urban youth. Data included 731 adolescents who participated in Project Northland Chicago and reported consuming alcohol in 7th grade. Logistic regression tested the effects of beverage-specific use on consequences (e.g., alcohol use in the past month, week, heavy drinking, and ever drunkenness). Compared to wine users, adolescents who reported drinking hard liquor during their last drinking occasion had increased odds of alcohol use during the past month (OR = 1.44; 95% CI = 1.01-2.05), past week (OR = 3.37; 95% CI = 1.39-8.18), and ever drunkenness (OR = 1.56; 95% CI = 1.07-2.29). Use of hard liquor was associated with increased risk of alcohol-related consequences. Early selection of certain alcoholic beverages (e.g., hard liquor) may result in negative health outcomes and problematic alcohol use over time.

Intimate partner violence: prevalence and risk factors for men in Cape Town, South Africa

This study examined the prevalence of and risk factors for intimate partner physical violence against women. Interviews were conducted with a sample of 1,378 men working in Cape Town municipalities. An average of 42.3% (95% CI: 39.6, 44.8) reported physical violence against a partner of the last 10 years, and 8.8% (95% CI: 7.3, 10.3) reported physical violence in the past year. After adjustment for age, occupational group, and race, the factors associated with use of violence against partners of the last 10 years were having no post-school training (OR = 2.10), witnessing parental violence in childhood (OR = 1.87), involvement in fights at work (OR = 2.73) and in communities (OR = 1.54), drug use (OR = 1.99), problem alcohol use (OR = 1.98), perceiving hitting women to be acceptable (OR = 4.54), frequent conflict (OR = 2.40), women's alcohol use (OR = 2.25), conflict about sex (OR = 2.16), and conflict about his infidelity (OR = 2.81). The study shows that ideas supportive of gender inequality and normative use of violence in different settings are major underlying factors for men's violence against partners.     

Depression and Elder Abuse and Neglect Among a Community-Dwelling Chinese Elderly Population

Differences in Tobacco Use Among Two-Year and Four-Year College Students in Minnesota

Abstract

Objective: This study compares tobacco use rates among two-year and four-year college students and explores the demographic variables that predicted that behavior. Participants: 9,931 students at 14 two-year and four-year colleges in Minnesota participated. Methods: Students at 11 schools completed an online survey, and students at 3 schools completed a paper survey in 2007. Results: After controlling for sex, age, ethnicity, relationship status, hours of work per week, and number of school credits, attending a two-year college predicted current and daily smoking (odds ratio [OR]) = 1.70, 95% confidence interval [CI] = 1.52–1.89; OR = 3.47, 95% CI = 2.94–4.11) and smokeless tobacco use (OR = 1.65, 95% CI = 1.32–2.06; OR = 1.64, 95% CI = 1.06–2.53). Conclusions: Although two-year college students comprise approximately two fifths of the college student population, surveys of college student tobacco use have focused nearly exclusively on four-year college students. Two-year college students should represent a priority population for tobacco control because attending a two-year college predicts increased tobacco use.     

Risk factors for computer visual syndrome (CVS) among operators of two call centers in São Paulo, Brazil

The aims of this study were to investigate work conditions, to estimate the prevalence and to describe risk factors associated with Computer Vision Syndrome among two call centers' operators in S?o Paulo (n = 476). The methods include a quantitative cross-sectional observational study and an ergonomic work analysis, using work observation, interviews and questionnaires. The case definition was the presence of one or more specific ocular symptoms answered as always, often or sometimes. The multiple logistic regression model, were created using the stepwise forward likelihood method and remained the variables with levels below 5% (p < 0.05). The operators were mainly female and young (from 15 to 24 years old). The call center was opened 24 hours and the operators weekly hours were 36 hours with break time from 21 to 35 minutes per day. The symptoms reported were eye fatigue (73.9%), "weight" in the eyes (68.2%), "burning" eyes (54.6%), tearing (43.9%) and weakening of vision (43.5%). The prevalence of Computer Vision Syndrome was 54.6%. Associations verified were: being female (OR 2.6, 95% CI 1.6 to 4.1), lack of recognition at work (OR 1.4, 95% CI 1.1 to 1.8), organization of work in call center (OR 1.4, 95% CI 1.1 to 1.7) and high demand at work (OR 1.1, 95% CI 1.0 to 1.3). The organization and psychosocial factors at work should be included in prevention programs of visual syndrome among call centers' operators.     

Perceptions of the Neighborhood Environment Associated With Walking at Recommended Intensity and Volume Levels in Recreational Senior Walkers

This study examined the relationship of perceived neighborhood environment factors with recommended volume and intensity of walking in recreational senior walkers. A sample of 85 seniors used an accelerometer and completed the ALPHA questionnaire. Binomial logistic regressions were conducted to detect associations. Perceptions about traffic safety (odds ratio [OR] = 4.395; 95% confidence interval [CI] = 1.024; 18.866) and pleasant environment (OR = 8.718; 95% CI = 1.803; 42.149) were positively related with the achievement of 10,000 steps per day, in older women. The perception of nearby parks was positively associated with the compliance with peak 30-minutes cadence above 100, in older men (OR = 14.353; CI 95% = 1.321; 15.591). No more significant associations were found between perceptions of the neighborhood environment and walking at recommended intensity and volume levels. These results indicated that community initiatives that encourage traffic safety, pleasant environment, and parks may be a promising direction to promote walking at recommended volume and intensity in senior walkers.     

Computer use and ulnar neuropathy: results from a case-referent study

We aimed to evaluate associations between vocational computer use and 1) ulnar neuropathy, and 2) ulnar neuropathy- like symptoms as distinguished by electroneurography. We identified all patients aged 18-65 years, examined at the Department of Neurophysiology on suspicion of ulnar neuropathy, 2001-2007. We mailed a questionnaire to 546 patients with ulnar neuropathy, 633 patients with ulnar neuropathy-like symptoms, and three community referents per case, matched on sex, age, and primary care centre. From a Job Exposure Matrix we extracted estimates of daily hours of computer use. The analysis was performed by conditional logistic regression.There were a negative association between daily hours of computer use and the two outcomes of interest. Participants who reported their elbow to be in contact with their working table for 2 hours or more during the workday had an elevated risk for ulnar neuropathy (OR=2.16, 95 % CI; 1.06-4.44).The two outcomes were not associated with daily hours of computer use. Findings suggested specific effects of pressure on the elbow, and might be an explanation for the overweight of left-sided outcomes in this primarily right-handed group. Preventive efforts would then be straightforward by providing appropriate arm support for the left arm and elbow.     

Minor psychiatric disorders among nursing workers--is there an association with current or former night work?

We aimed at analyzing whether Minor Psychiatric Disorders (MPD) is associated to night work either currently or in the past. A cross-sectional study was conducted at three public hospitals in Brazil, with female nursing workers. Data collection (N=1,134) was based on a comprehensive questionnaire that included the self-reported questionnaire (SRQ-20) for screening of MPD. Former night workers were subdivided into three groups according to their reasons for leaving night work: (i) directly related to work, (ii) related to better reconcile with studies or another job, and (iii) related to health, sleep, fatigue or stress. Binomial logistic regression was performed, with adjustment for potential confounders. A dose response gradient was observed between current night work and MPD (OR=1.5; 95% CI: 1.1-2.2 and OR=2.1; 95%CI: 1.5-3.1 for those who worked up to five nights and six or more nights per 2-week span, respectively). Potential detrimental effects of night work were confirmed. The association between working at night and MPD was not restricted to current night workers as workers who left night work for health/fatigue/sleep/strain also showed higher chances of reporting MPD (OR=1.8;95%CI:1.14-2.90). Results contribute to the scientific debate on the impact of night work on health and wellbeing.     

The impact of childhood sexual abuse and intimate partner violence on sexually transmitted infections

Childhood sexual abuse (CSA) and adult intimate partner violence (IPV) have both been found to be associated with sexually transmitted infections (STIs) independently, but studies of STIs have rarely looked at victimization during both childhood and adulthood. This paper examines the relationship between CSA, IPV and STIs using data from a nested case-control study of 309 women recruited from multiple health care settings. Overall, 37.3% of women experienced no violence, 10.3% experienced CSA only, 27.3% experienced IPV only, and 25.0% experienced both CSA and IPV. Having ever been diagnosed with an STI was associated with violence (CSA only, odds ratios [OR] = 2.8, 95% confidence intervals [CI] = 1.0-7.5; IPV only, OR = 2.2, 95% CI = 1.0-4.9; CSA and IPV: OR = 4.0, 95% CI = 1.7-9.4), controlling for demographic characteristics. Women who experienced CSA were younger when they were first diagnosed. Understanding how both childhood and adult victimization are associated with diagnosis of STIs is important to reducing the incidence and prevalence of STIs, as well as the associated consequences of STIs.     

Strength-training behavior and perceived environment among Japanese older adults

The authors examined the relationship between strength-training behavior and perceived environment in older Japanese adults. An Internet-based survey was conducted of 293 adults age 68.2 ± 2.8 yr. The dependent variable was regular strength-training behavior. The IPAQ environment module, access to facilities for strength training, and home equipment for strength training were environmental factors. Logistic-regression analysis was employed. After demographic variables (gender, age, educational background, household income, body-mass index, self-rated health status, smoking habit, and residential area) were adjusted for, home equipment for strength training (OR = 2.14, 95% CI = 1.50-3.06), access to facilities for strength training (OR = 2.53, 95% CI = 1.32-4.85), and observing active people (OR = 2.20, 95% CI = 1.06-4.58) were positively correlated with regular strength-training behavior. In conclusion, environmental factors associated with strength-training behavior were access to facilities for strength training, having home equipment for strength training, and observing active people.     

Suicidality and Sexual Orientation in Five Continents: Asia, Australia, Europe, North America, and South America

This study examined the relation between suicidality and sexual orientation in an intercontinental sample (Asia, Australia, Europe, North America, and South America). Participants responded to a survey hosted on the Internet Website of an international news organization. Categorical analyses compared homosexual and bisexual respondents' history of suicide attempts and suicide ideations to those of heterosexual respondents, by total sample, males only, and females only. A relation between male sexual orientation and suicide attempts was found for every continent except Europe (odds ratio [OR] 1.5; 95% confidence interval [CI] = 0.3, 6.9). A relation between female sexual orientation and suicide attempts was not found in any continent except North America (OR = 2.1; 95% CI % 1.7, 2.5). These data provide preliminary evidence of intercontinental variation in the relation between suicidality and sexual orientation.     

Evaluation of a personal device in reducing the risk of low back disorders during stooped work

Adoption of the stooped posture in the workplace is widespread throughout the world in agriculture, construction, and mining. This type of posture has been established as a risk factor for developing low back disorders (LBDs). The purpose of this study is to evaluate a personal weight transfer device as a possible intervention to reduce the load on the lumbar spine, thereby reducing the risk of developing LBDs. Eighteen healthy subjects performed stooped posture tasks in a laboratory study designed to simulate harvesting of low-growing crops. Results showed that when wearing the device in the static stooped posture, biceps femoris activity was reduced by 17%, lumbar flexion was reduced by 12%, ankle plantar-flexion increased by 5%, and the lumbar erector spinae of those subjects who did not experience flexion-relaxation of the erector spinae was reduced by 26%. Hip and knee flexion were not significantly altered. Therefore, the device may be beneficial for those with existing LBDs, and who use the stooped posture routinely.     

Impact of metabolic syndrome and its components on kidney stone in aging Taiwanese males

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.

Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.

Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?p?Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone.
