People with visual impairments experience various challenges in the workplace such as under-employment, structural, and attitudinal barriers. Workplace accommodations are instrumental in assisting individuals to complete essential functions of their jobs and to increase job tenure and satisfaction. However, workplace accommodations are under-utilized. The current study examined influences of psychosocial and demographic factors on decisions to request accommodations amongst people with visual impairments. Participants included 116 people with visual impairments (e.g., female = 63.9%, Caucasian = 81%) from agencies and organizations serving people with visual impairments within United States. The results following logistic regression show that increased levels of psychosocial factors (i.e., self-efficacy in requesting accommodations and goal setting, non-personal cost related to accommodation, knowledge related to Americans with Disabilities Act (ADA), and accommodation policies and procedures) predicted participants’ decision to request accommodations. In addition, participants aged 55 or more and those with a high school degree or lower were less likely to request accommodations. Rehabilitation interventions for enhancing work participation self-efficacy in employees with visual impairment, as well as knowledge on ADA and accommodation policies and procedures, would create a more inclusive and accepting work environment for employees with visual impairment.

Twinning is rare among humans, but there is much variability among populations. Several studies show that certain demographic and socioeconomic factors, such as maternal age, mother’s educational level and income, influence twinning rate. There is no background of analytical studies of twins in Uruguay. To the best of our knowledge, this is the first study that has focused on describing and analyzing Uruguayan twinning rates over a period of 17 years (1999–2015). The birth data were collected from the website of Uruguay’s Ministry of Public Health. Economic data were obtained from Uruguay’s Instituto Nacional de Estadísti’s website for the period 2001–2013, since these variables are defined specifically for that period of time. The statistical software R (The R Project for Statistical Computing) was used. The twinning rate varied from 8.51 to 13 in the studied period. Montevideo has the highest median and the smallest variability in comparison with the other departments. In Uruguay (1999–2015), the highest twinning rate (28.94%) was observed in women aged 45 and older. The analysis also showed a relationship between twin birth rates and the mother’s educational level. In three regions of the country (West, Center and East), twin births show a random pattern but in the other two (North and Metropolitan), there is an increasing trend in the number of twins over time. In conclusion, this study recognizes social, economic and demographic factors that influence in the rate of twin births in Uruguay.

Background: Age and time post-diagnosis can significantly impact cognitive and motor functions in multiple sclerosis (MS); however, studies often fail to account for these factors when assessing differences between disease courses. Objectives: Examine differences between relapsing-remitting and progressive MS in cognition, motor function, and everyday activities, controlling for age, education, and time post-diagnosis. Methods: Twenty-one persons with relapsing-remitting MS (RRMS group), 21 with progressive MS (PMS group), and 21 healthy participants (HCs), matched on age, education, and time post-diagnosis, completed tests of cognitive abilities, motor functions, and everyday functional activities. Results: The two groups with MS did not differ on cognitive performance. Poorer performance in processing speed was noted in both MS groups in comparison with the HC group. Motor function was worse for the PMS group compared with the HC and RRMS groups. The RRMS group showed poorer upper limb functioning compared to the HC group. The PMS group had more difficulty with everyday activities as compared with both the RRMS and HC group. Conclusions: When comparing differences in functioning between MS disease courses, attention should be paid to the demographic characteristics of the samples. (JINS, 2018, 24, 139–146)

Red and processed meat (RPM) intake varies widely globally. In some high-income countries (HIC) the last decade has witnessed an overall decline or stabilisation in the consumption of RPM, in contrast to emerging economies where its consumption continues to increase with rising income and rapid urbanisation. The production and consumption of RPM have become major concerns regarding the environmental impacts of livestock in particular, but also because of associations between high RPM consumption and diet-related non-communicable disease. Therefore, it is important to identify socioeconomic and demographic drivers of the consumption of RPM. This paper explores how consumption of RPM differs with age, gender, socioeconomic status and in different global contexts. There are some key socioeconomic and demographic patterns in RPM consumption. Men tend to consume RPM more often and in higher quantities, and there is evidence of a social gradient in HIC, with lower socioeconomic groups consuming RPM more often and in larger quantities. Patterns for consumption with age are less clear cut. It is apparent that consumers in HIC are still consuming high levels of RPM, although the downward shifts in some socioeconomic and demographic groups is encouraging and suggests that strategies could be developed to engage those consumers identified as high RPM consumers. In low- and middle-income countries, RPM consumption is rising, especially in China and Brazil, and in urban areas. Ways of encouraging populations to maintain their traditional healthy eating patterns need to be found in low- and middle-income countries, which will have health, environmental and economic co-benefits.

We investigated the effect of climatic, demographic factors and intra-country geographical variations on the incidence of invasive meningococcal disease (IMD) in Italy. For this purpose, incidence rates of IMD cases reported in Italy between 1994 and 2012 were calculated, and a cluster analysis was performed. A geographical gradient was determined, with lower incidence rates in central and southern Italy, compared to the northern parts, where most clusters were observed. IMD rates were higher in medium-sized towns than in villages. Adults were at lower risk of IMD than children aged ⩽4 years. IMD incidence tended to decrease with increasing monthly mean temperatures (incidence rate ratio 0·94, 95% confidence interval 0·90–0·99). In conclusion, geographical variations in IMD incidence were found, where age and temperature were associated with disease occurrence. Whether geographical variations should be considered in national intervention plans is still a matter for discussion.

Few studies have specifically focused on characteristics associated with consumption of combined fatty-salted and fatty-sweetened foods, whereas their identification could be useful for defining effective public health measures. The aim of the present study was to investigate the association between demographic, socio-economic, lifestyle and health characteristics and consumption of these types of food in a general sample of French adults. Dietary intake was assessed using a minimum of six 24 h dietary records collected over a 2-year period in 6240 subjects aged 35–60 years who participated in the Supplémentation en VItamines Minéraux et AntioXydants cohort study. Associations of individual characteristics with high and intermediate consumption of fatty-sweetened and fatty-salted foods were assessed using multivariate polytomic logistic regression models. Risk of moderate or high consumption of fatty-salted foods decreased with increasing age. Current smokers, drinkers, individuals with overweight and with hypertension were more likely to consume moderate or high amounts of such foods. Risk of moderate or high consumption of fatty-sweetened foods decreased with increasing age. Women, individuals living as a couple, moderate drinkers and persons with low or medium physical activity level were more likely to consume moderate or high amounts of such foods. Lower educated subjects, current smokers, heavy drinkers and individuals with severe hypertriacylglycerolaemia were less likely to have moderate or high consumption. Consumption of fatty-sweetened and fatty-salted foods varied according to demographic, lifestyle and health characteristics. Common unhealthy behaviours such as smoking, low physical activity and alcohol drinking, associated with high consumption of these food groups, may help to effectively target public health efforts.

Identifying county-level sociodemographic and economic factors associated with the incidence of enteric disease may provide new insights concerning the dynamics of community transmission of these diseases as well as opportunities for prevention. We used data from the National Notifiable Diseases Surveillance System, the U.S. Census Bureau, and the Health Resources and Services Administration to conduct an ecological analysis of 26 sociodemographic and economic factors associated with the incidence of salmonellosis, shigellosis, and E. coli O157:H7 infections in US counties for the period 1993 to 2002. Our study indicates that race, ethnicity, place of residence, age, educational attainment, and poverty may affect the risk of acquiring one of these enteric bacterial diseases. The lack of specificity of information regarding salmonellae and shigellae serotypes may have led to less specific associations between community-level determinants and reported incidence of those diseases. Future ecological analyses should use serotype-specific data on incidence, which may be available from laboratory-based surveillance systems.

Demographic factors and cognitive impairment have been found previously to have associations with outcome after brain injury. Kendall and Terry (1996) suggest that preinjury psychosocial functioning, neurological factors, and cognitive impairment have a direct relationship with multidimensional psychosocial adjustment, but that cognitive impairment also has an indirect relationship by means of the mediation of appraisal and coping variables. The aim of this study was to explore these theoretical relationships at very late stages of recovery after brain injury. A total of 131 participants who were more than 10 years after injury (mean = 15.31 yr) completed a neuropsychological assessment, plus outcome measures that included employment status, community integration, life satisfaction, quality of life (QoL), and emotion. Results indicated that injury severity was predictive of life satisfaction; gender and relationship status predicted community integration; and age at injury predicted employment status. Impairment in working memory directly predicted all outcomes except QoL and anxiety. An indirect relationship was also evident between working memory, life satisfaction, and depression. Results partially support Kendall and Terry's model but the variables that significantly influence outcome seem to be determined by the outcome dimensions selected. (JINS, 2006, 12, 350–358.)

This paper examines aspects of the epidemiology of affective disorders in Scotland. Results from 3 investigations are described, each one indicative of a particular research approach (the use of national, case-register and direct-interview based data). In Part I of the paper secular trends in Scottish national and local (Edinburgh city) first admission rates of affective disorders, based upon ICD-9, are examined. The results, based upon the national data, show that during the last two decades the male admission rate declined by 29.4% and the female rate by 37.3%. However, the female rate has remained 1.8 to 2.2-fold that of the male rate throughout this period. Further investigation of these changes was undertaken after dividing the affective disorder category into either the “affective psychoses” or the “depressive neuroses”. Results revealed that whilst there was only a slight change in the Scottish national rate of affective psychoses, marked decreases in rates were revealed for the depressive neuroses for both sexes (males by 39.4% and females by 39.3%). Age-specific secular trends also demonstrated the extent to which the older age groups of both sexes experienced the highest rates of affective psychoses.

Results based upon first admissions for affective disorder to the Royal Edinburgh Hospital over the years 1976-1987 showed that the overall male rate had remained relatively unchanged, whilst that for females had declined by about 24%. Subsequent analysis showed that the rates for affective psychoses had declined over the 12 years to a level which for the females was close to the national rate but that the male rate for these conditions had remained (in 1985) at 70% above the Scottish national rate.

Part II of this paper presents results from two further studies concerned with investigating rates of affective disorder amongst women. The first of these was a general population survey of a random sample, the second a hospital study. Both studies were designed to be complementary, in that each was based upon samples of women living in the same geographical area of Edinburgh city. Results revealed that the hospital prevalence estimate for affective disorders was only about 1% of the community estimate, but over 5% of the community inception rate. Analyses examining the demographic correlates of affective disorders revealed the extent to which age and marital status differentially determined the ease with which women entered hospital care. Results revealed that being single and of older age was associated with an increased chance of receiving treatment for women with affective disorders.
