Sexual Activity and Depressive Symptoms in Later Life: Insights from Jamaica.

Objectives: To explore relationships between sexual activity and depressive symptoms in urology and gynecology out-patients aged 50 years and older.Methods: Depressive symptoms were assessed using Zung Self-Rating Depression Scale. Sexual activity was measured by interviewer-administered questionnaires assessing relationships, intimacy and sexual function (N = 557). Aging and sexual activity were discussed in focus groups (N = 52).Results: More men (51%) than women (41%) reported engagement in sexual intercourse and approximately 40% of men reported sexual activities in the past 4 weeks. The mean number of sex-related complaints per woman was 1.5 (Standard Deviation, 1.2). Approximately four of every ten men reported difficulty with erectile function. Men placed high value on sexual intercourse while women also embraced other activities. After controlling for demographic and health variables, men who reported sexual activity in the past 4 weeks had depressive symptom scores approximately five points lower than those who reported no sexual activity. Each additional sexual complaint was associated with a two-point increase in depressive symptoms scores in women.Conclusions: Higher depressive symptom scores are associated with reduced sexual activity in men and increased sexual complaints in women. Sexual activities remain important for older adults, despite declining sexual function and men place higher value on sexual intercourse than women.Clinical implications: Mental health assessments and sexual activity history should be included in routine healthcare consultations in persons 50 and over.

Zarit burden interview among caregivers of community-dwelling older adults in a caribbean setting (Jamaica): Reliability and factor structure.

The Zarit Burden Interview has been the most popularly used tool for measuring caregiver burden and with the 60 years and over population in Jamaica and developing countries expected to increase, caregiver burden and its assessment assume increased importance. Establishing the reliability and underlying factor structure of instruments such as the ZBI is critical. This study sought to determine the reliability of the Zarit Burden Interview and to assess its underlying factor structure. The ZBI was administered to 180 caregivers of community dwelling older persons in Jamaica in a nationally representative sample across four geographic health regions in 2016. The factor structure was identified using exploratory factor analysis (EFA) with Varimax rotation. Cronbach's alpha was used to assess internal consistency/reliability of the instrument. The internal consistency/reliability of the ZBI instrument was high (Cronbach's α = 0.859) and the corrected item-total correlations ranged from 0.134 to 0.730. The ZBI mean score was found to be 16.92 ± 12.04. EFA produced a six-factor model comprised of 19 items which explained 48.97% of total variance, and was subsequently reduced to four (37.27% of total variance) via the use of parallel analysis and scrutiny of confidence intervals. The four factors identified were 'personal strain', 'social relations disruption', 'resource strain/imbalance' and 'role intensity'. The ZBI-22 tool is a reliable instrument for evaluating caregiver burden among community dwelling older persons in Jamaica. A four factor model has emerged providing greater insights on the underlying constructs of the ZBI, the most widely used caregiver burden assessment tool.

Caregivers of Older Persons in Jamaica: Characteristics, Burden, and Associated Factors.

OBJECTIVE: The objective of this study was to determine and characterize caregiver burden among caregivers of community-dwelling older persons in Jamaica. METHOD: A nationally representative cross-sectional study was done among persons providing noninstitutional care for a single person (≥60 years). The Zarit Burden Interview (ZBI) and a structured questionnaire were administered to 180 caregivers from four geographic health regions. RESULTS: The ZBI scores ranged from 0 to 56 (median = 15). Independently associated factors were relationship to care recipient and age. Children/grandchildren had higher caregiver burden scores than formally employed caregivers (odds ratio = 2.9: 95% confidence interval: [1.02, 8.34]). Compared with caregivers 35 to 44 years, those aged 45 to 65 were almost 5 times more likely to report higher caregiver burden scores. CONCLUSION: Caregiver burden as identified by the ZBI was low. Age (45-65 years) and being the child/grandchild of the care recipient were independently associated with greater caregiver burden. Interventions to address caregiver burden must embrace strategies that recognize that these factors.

Socio-demographic, Health and Functional Status Correlates of Caregiver Burden Among Care Recipients Age 60 Years and Older in Jamaica.

The provision of care to older persons can impose significant burden on those providing care, burdens influenced by care recipient characteristic, caregiver attributes and availability of social support. This paper focuses on identifying relationships between caregiver burden and the socio-demographic, health and functional status attributes of care recipients age 60 years and older in Jamaica. A nationally representative cross-sectional study was done among persons providing non-institutional care for a single person 60 years and older. Data were obtained from a total of 180 caregivers from the four geographic health regions of Jamaica using the Zarit Burden Interview and a 44-question structured questionnaire. Associations between caregiver burden and socio-demographic, health and functional status of care recipients were examined and logistic regression applied to ascertain independent predictors of caregiver burden. The results revealed statistically significant relationships between caregiver burden and care recipients' receipt of conditional cash transfer grants and the ability to toilet independently. In multivariate analysis, ability to toilet remained a significant predictor of caregiver burden-Caregivers who had care recipients who were able to toilet independently were 71% less likely to have mild to severe caregiver burden compared to those who had care recipients that were not able to toilet (OR 0.29; 95% CI 0.14-0.57). Families, health care providers, social workers, state actors and caregivers should take this into account as they develop strategies to mitigate associated caregiver burden.

Proportion of Dementia Explained by Five Key Factors in Jamaica.

BACKGROUND: Dementia has no known cure and age is its strongest predictor. Given that populations in the Caribbean are aging, a focus on policies and programs that reduce the risk of dementia and its risk factors is required. OBJECTIVE: To estimate the proportion of dementia in the Jamaican setting attributable to key factors. METHODS: We analyzed the contribution of five modifiable risk factors to dementia prevalence in Jamaica using a modified Levin's Attributable Risk formula (low educational attainment, diabetes, smoking status, depression, and physical inactivity). Four sources of data were used: risk factor prevalence was obtained from the Jamaica Health and Lifestyle Survey, 2008, relative risk data were sourced from published meta-analyses, shared variance among risk factors was determined using cross-sectional data from the Health and Social Status of Older Persons in Jamaica Study. Estimated future prevalence of dementia in Jamaica was sourced from a published ADI/BUPA report which focused on dementia in the Americas. We computed the number of dementia cases attributable to each risk factor and estimated the effect of a reduction in these risk factors on future dementia prevalence. RESULTS: Accounting for the overlapping of risk factors, 34.46% of dementia cases in Jamaica (6548 cases) were attributable to the five risk factors under study. We determined that if each risk factor were to be reduced by 5% -10% per decade from 2010-2050, dementia prevalence could be reduced by up to 14.0%. CONCLUSION: As the risk factors for dementia are shared with several of the main causes of death in Jamaica, a reduction in risk factors by even 5% can result in considerable public health benefit.

Breast Cancer in Jamaica: Trends From 2010 to 2014-Is Mortality Increasing?

PURPOSE: This study sought to provide a detailed analysis of breast cancer-specific mortality in Jamaica on the basis of reported deaths between 2010 and 2014. METHODS: A cross-sectional study was done to analyze breast cancer-specific mortality data from the Registrar General's Department, the statutory body responsible for registering all deaths across Jamaica. RESULTS: A total of 1,634 breast cancer-related deaths were documented among Jamaican women between 2010 and 2014, which accounted for 24% of all female cancer deaths. The age-standardized breast cancer mortality rate increased from 21.8 per 100,000 in 2010 to 28 per 100,000 in 2014 for the total female population. The overall difference in breast cancer mortality rates between the 2014 and 2010 rates was not statistically significant (P = .114). Analysis of the year-by-year trend reflected by the annual percentage of change did show, however, a statistically significant increasing trend in breast cancer mortality (P = .028). Mortality rates varied by age, with statistically significant annual increases observed in the 35-44-, 65-74-, and ≥ 75-year age groups (P = .04, .03, and .01, respectively). CONCLUSION: Breast cancer remains the leading cause of death among Jamaican women. Despite global advances in breast cancer screening and management, breast cancer remains a major public health challenge and represents a public health priority in Jamaica. The increasing breast cancer-specific mortality in Jamaica over the 5-year period contrasts with decreasing mortality rates among US women with breast cancer. This study highlights the critical need to address the implementation of a national organized breast cancer screening program in Jamaica and to focus future research efforts on the biology of breast cancer, especially among young Jamaican women.

Performance and Receiver Operating Characteristics of the Mini-Mental State Examination Instrument in Detecting Dementia in a Rapidly Aging Developing Country (Jamaica).

OBJECTIVE: To examine the performance of the Mini-Mental State Examination (MMSE) in community-dwelling older persons in a developing country (Jamaica) undergoing rapid population aging. METHODS: An embedded validity study was conducted utilizing participants from a nationally representative sample of 2782 older persons. Standardized MMSE scores were obtained for study participants. A random selection of 170 persons with MMSE scores greater than 20 and 170 persons with scores 20 or less was done. Field staff were trained to apply the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for the diagnosis of dementia. In total, 300 participants (167 participants with MMSE score of 20 or less, 133 participants with scores greater than 20) were assessed and categorized according to dementia status. Performance characteristics of the MMSE tool were determined for study participants and appropriate adjustment and analyses subsequently applied to facilitate extrapolation to the nationally representative sample. RESULTS: The mean MMSE scores for participants with score of 20 and less was 17.1 (standard deviation [SD] = 3.2) and 24.5 (SD = 2.8) for those with scores greater than 20. Dementia was identified in 34 participants. The receiver operating characteristic curve for MMSE scores in relation to dementia diagnosis had an area under the curve value of 0.935 (95% confidence interval, 0.893-0.977). The optimal MMSE cut-point was 18/19 and was consistently so regardless of age category, gender, educational level, and number of chronic illnesses. CONCLUSION: There is merit in using the MMSE examination as a screening tool for dementia in Jamaica. The findings of this study coupled with widespread use and familiarity among practitioners give credence to the MMSE as a reasonable screening tool for dementia in Jamaica-rapidly aging society.

Predictors of Health Service Utilization Among Older Men in Jamaica.

OBJECTIVES: To determine the relative influence of sociodemographic, socioeconomic, psychosocial, and health variables on health service utilization in the last 12 months. METHODS: Data were analyzed for 1,412 men ≥60 years old from a 2012 nationally representative community-based survey in Jamaica. Associations between six health service utilization variables and several explanatory variables were explored. Logistic regression models were used to identify independent predictors of each utilization measure and determine the strengths of associations. RESULTS: More than 75% reported having health visits and blood pressure checks. Blood sugar (69.6%) and cholesterol (63.1%) checks were less common, and having a prostate check (35.1%) was the least utilized service. Adjusted models confirmed that the presence of chronic diseases and health insurance most strongly predicted utilization. A daughter or son as the main source of financial support (vs self) doubled or tripled, respectively, the odds of routine doctors' visits. Compared with primary or lower education, tertiary education doubled [2.37 (1.12, 4.95)] the odds of a blood pressure check. Regular attendance at club/society/religious organizations' meetings increased the odds of having a prostate check by 45%. DISCUSSION: Although need and financial resources most strongly influenced health service utilization, psychosocial variables may be particularly influential for underutilized services.

Patterns of depressive symptoms among younger elderly (60-74 years old) and older elderly (≥75 years old) in Jamaica.

OBJECTIVES: We sought to explore factors associated with depressive symptom severity among older persons (≥60 years of age) and to compare the depressive symptoms commonly experienced by older elderly (≥75 years) with those commonly experienced by younger elderly (<75 years). DESIGN: Secondary analysis was conducted on data from a nationally representative survey. SETTING: Four parishes in Jamaica. PARTICIPANTS: A total of 2,943 older community dwellers participated. MEASUREMENTS: The survey included the Zung Self-rating Depression Scale (ZSDS), the Mini Mental State Examination (MMSE), and items on age, sex, and educational level. Linear regression analysis was used to determine the association between ZSDS score and: age, sex, MMSE score, and educational level. Logistic regression analysis was used to determine, for each ZSDS item, whether particular responses were more associated with older or younger elderly. RESULTS: Higher ZSDS scores were associated with increasing age (B = 0.13, p < 0.001), lower MMSE score (B = -0.42, p < 0.001), the female sex (B = 3.52, p < 0.001), and lower educational level (B = -1.27, p < 0.001). The ZSDS items that were endorsed significantly more (p < 0.05) by older elderly related to negative evaluations about their functionality and value. Hopelessness was also more prominent among the older elderly. The items that were endorsed significantly more (p < 0.05) by the younger elderly had less of a focus. CONCLUSION: Among older persons, increasing age was associated with marginally higher levels of depressive symptoms. Female gender, cognitive deficits, preoccupations about value and functionality, and feelings of hopelessness may serve as useful screening parameters.

Alcohol use, depression, and life satisfaction among older persons in Jamaica.

BACKGROUND: We aimed to determine the prevalence of alcohol use among older Jamaicans as well as to explore among this population the relationships between alcohol use and: age, sex, depressive symptoms, and life satisfaction. Although the nature of these relationships among the proposed study population were uncertain, in other settings alcohol use has tended to decline with increasing age, occur more commonly among men than women, and show non-linear relationships with depressive symptoms and life satisfaction. METHODS: Data gathered by two-stage cluster sampling for a nationally representative health and lifestyle survey of 2,943 community-dwelling older Jamaicans, aged 60 to 103 years, were subjected to secondary analysis using the Student's t-test and χ 2 test as appropriate. RESULTS: Current alcohol use was reported by 21.4% of the participants. It steadily declined with age and was six times more prevalent among men (37.6%) than women (6.2%). These findings were statistically significant as were associations of current alcohol use with comparatively lower levels of depressive symptoms. Current alcohol use was also more prevalent among persons who were either highly satisfied or highly dissatisfied with their lives, compared to others who had levels of life satisfaction between these two extremes. CONCLUSIONS: Current alcohol use among older Jamaicans occurs primarily among men, declines with increasing age, and is associated with a relatively low likelihood of depression. It is also associated with very high and very low levels of life satisfaction.

The Health of Office-Based Workers in Kingston, Jamaica.

The health status of Jamaican workers was evaluated as a baseline for workplace health promotion interventions. Socio-demographic, health status, and lifestyle data were collected from 1,087 employees. Blood pressure, glucose and cholesterol levels, and body mass index were measured for study participants. The most common illness reported by the study participants was migraine headaches (16.0%), followed by hypertension (13.5%) and asthma (6.1%). Based on blood pressure measurements, 34.1% were pre-hypertensive (120-139/80-89 mmHg), 13.1% had Stage 1 hypertension (140-159/90-99 mmHg), and 2.3% Stage 2 hypertension (≥160/≥100 mmHg). Furthermore, 33% were overweight, 16.7% were obese, and 10% were extremely obese. Most (55.1%) of the study participants reported excessive fast-food consumption in the last 7 days. The high rates of obesity, hypertension, and fast-food consumption reported in this study emphasized the need for focused health promotion strategies. Universality across institutions presented an excellent opportunity for national workplace health intervention programs.

Participation in Social Activities and the Association with Socio-Demographic and Health-Related Factors among Community-Dwelling Older Adults in Jamaica.

Social participation is critical for maintaining independence and facilitating active ageing. The aim of this paper is to describe participation in social activities among older adults in Jamaica and to identify independently associated socio-demographic and health characteristics. We analysed data from a nationally representative, community-based survey of 2943 persons 60 years and older. Sixty-three percent of older adults attended religious services and 60 % were visited by friends at least once per month in the 12 months preceding the survey. Age was not independently associated with social participation. Persons with post-secondary level education were twice as likely as those with primary education or less, to be visited by friends and to attend meetings of formal organisations. Men, persons not in union, and those with less functional independence had reduced odds of attending meetings of formal organisations. These variables were however not independently associated with having visits with friends. Persons with a positive depression screen were between 42 % and 44 % less likely to be visited by friends. Persons who received an income through livestock/farming were more likely to visit or be visited by friends. The variables independently associated with social participation vary depending on the type of social activity considered. Where possible, health and social interventions should focus on prevention, delay and reversal of risk factors associated with reduced social participation. Social participation programmes should be prioritized and be informed by input from older adults. Future research should include other forms of social interactions and clarify older adults' perceptions of their quality.

The prevalence and associated demographic factors of dementia from a cross-sectional community survey in Kingston, Jamaica.

OBJECTIVES: Using a cross-sectional community survey, the authors aimed to estimate the prevalence of dementia among a sample of older Jamaicans and to identify associated demographic factors. METHODS: From February to July 2010, persons of age ≥60 years were randomly selected from two communities in Kingston, Jamaica and screened with the Mini Mental Status Examination (MMSE). All MMSE-positive participants and an equal number of matched MMSE-negative participants underwent definitive diagnostic evaluation for dementia using the Clinical and Diagnostic Assessment Procedure for Dementia. Subsequently derived MMSE sensitivity and specificity measures from the subsample were used to estimate the overall prevalence of dementia (primary outcome). Chi square, Fisher's Exact, Exact, Spearman's correlation and t-tests were used to explore associations of dementia with age, gender, educational level and socioeconomic status. Statistical significance was taken as p < 0.05. RESULTS: Two hundred participants were recruited. Age-standardized prevalence rates of dementia were 5.07% (standardized to the Jamaican population) and 5.32% (standardized to the West Europe population). Dementia was more prevalent among older persons (Spearman's rho = 0.31; p < 0.001); no other significant associations were found. CONCLUSIONS: Dementia prevalence found in this study is lower than figures from previous Caribbean reports. The older persons are disproportionately affected.

Ageing in place: implications of morbidity patterns among older persons--findings from a cross-sectional study in a developing country (Jamaica).

AIM: This paper describes morbidity patterns among older people, relevant health-care resources in a localised population in a developing country (Jamaica) and implications for ageing in place in the community. METHODS: Local morbidity patterns among older people were determined in Jamaica from a 2007 cross-sectional study involving record searches at major hospitals and clinics. Age-specific morbidity distributions were compiled. Data on health-care staff complement were also collected. RESULTS: Non-communicable diseases predominate in older people in Jamaica; 50% of diagnoses related to cardiovascular disorders and diabetes. Staff-to-population ratios were low compared with other international data. CONCLUSION: A high prevalence of non-communicable disease coupled with inadequate staffing threatens the likelihood of ageing in place in the Jamaican community. Secondary prevention efforts and social support services which enhance ageing in place are needed.

Re-testing theories on the correlations of health status, life satisfaction and happiness.

BACKGROUND: Empirical evidences have shown that happiness, life satisfaction and health status are strongly correlated with each other. In Jamaica, we continue to collect data on health status to guide policies and intervention programs, but are these wise? AIMS: The current study aims to fill the gap in the literature by examining life satisfaction, health status, and happiness in order to ascertain whether they are equivalent concepts in Jamaica as well as the coverage of the estimates. MATERIALS AND METHODS: The current study used a cross-sectional survey of 2000 men 55 years and older from the parish of St. Catherine in 2007 which is it also generalizable to the island. A132-item questionnaire was used to collect the data. The instrument was sub-divided into general demographic profile of the sample; past and Current Good Health Status; health-seeking behavior; retirement status; social and functional status. Ordinal logistic regression techniques were utilized to examine determinants of happiness, life satisfaction and health status. RESULTS: Happiness was correlated with life satisfaction - Pseudo r-squared = 0.311, -2LL = 810.36, χ(2) = 161.60, P < 0.0001. Life satisfaction was determined by happiness - Pseudo r-squared = 0.321, -2LL = 1069.30, χ(2) = 178.53, P < 0.0001. H ealth status was correlated with health status age, income, education and area of residence - Pseudo r-squared = 0.313, -2LL = 810.36, χ(2) = 161.60, P < 0.0001. CONCLUSION: The current study refuted the empirical finding that self-reported happiness depends on perceived health status for older men in Jamaica.

Difference in social determinants of health between men in the poor and the wealthy social strata in a Caribbean nation.

BACKGROUND: Studies that have examined social determinants of health have made their investigations on the population, but none have reviewed them from the perspective of particular social hierarchies. AIM: The study examined the factors determining the self-reported health of men of different socioeconomic status, by using models derived through econometric analyses. MATERIALS #ENTITYSTARTX00026; METHODS: The study used a sample of 6,474 respondents: 2,704 from the two poor quintiles and 3,770 from the two wealthy quintiles. The survey used a random stratified probability sampling technique and involved the use of self-administered questionnaires. Multiple logistic regression technique was used to identify variables which are associated with health conditions of men in the two social hierarchies. RESULTS: The findings revealed that the self-reported health of men in the two wealthiest quintiles were substantially influenced by private health insurance coverage (Odds Ratio (OR) = 32.9, 95%CI: 20.64, 52.45) and age of respondents (OR = 1.03, 95%CI: 1.02, 1.04) This was similar for men in the two poorest income quintiles; private health insurance coverage (OR = 16.97, 95%CI: 10.18, 28.27) and age (OR=1.05, 95%CI: 1.03, 1.06). Negative affective psychological conditions, consumption and medical expenditure affected the self-reported health of those in the two wealthiest quintiles, while positive affective, secondary levels of education and living alone influenced those in the two poorest quintiles. CONCLUSION: This research serves as a foundation for further work relating to the determinants of self-reported health conditions, inequity across socio-economic strata for men, and how patient care should be addressed.

Social determinants of physical exercise in older men in Jamaica.

BACKGROUND: Physical activity interventions have been demonstrated to improve health-related quality of life and to be of special benefit to older adults with specific chronic conditions including arthritis, hypertension, diabetes mellitus, and heart disease. AIM: This study examined the extent and social determinants of physical exercise in elderly men in Jamaica. MATERIALS AND METHODS: A sample of 2,000 men 55 years of age and older was extracted from a total of 33,674 males in the parish of St. Catherine. A 132-item questionnaire was used to collect the data. A stratified random sampling technique was used to draw the sample. Descriptive statistics were used to provide background information on the sub-sample, and logistic regressions were utilized to model physical exercise. RESULTS: Of the respondents, 55.4% indicated good health status, 51.0% lived in rural areas; 10.4% had moderate to high functional dependence and 67.3% reported that they did some form of physical exercise. Of those who indicated involvement in physical exercise (n = 1,345), 77.2% jogged, ran, and/or walked; 13.3% did aerobics; 4.7% swam; 2.0% cycled and 0.6% did push-ups or sit-ups. The variables that predicted being engaged in physical exercise were education; age of respondents; current good health status; household head; health plan; employment status, and social support. CONCLUSION: Most of the elderly men were engaged in some form of physical activity and had good health. Age and good health status were the most influential social determinants of physical exercise. However, effective interventions to promote physical activity in older men in Caribbean countries such as Jamaica deserve wide implementation.

Health literacy and health seeking behavior among older men in a middle-income nation.

Health literacy is a measure of the patient's ability to read, comprehend and act on medical instructions. This research article examines health literacy and health-seeking behaviors among elderly men in Jamaica, in order to inform health policy. This is a descriptive cross-sectional study. A 133-item questionnaire was administered to a random sample of 2,000 men, 55 years and older, in St Catherine, Jamaica. In this study, 56.9% of urban and 44.5% of rural residents were health literate. Only 34.0% of participants purchased medications prescribed by the medical doctor and 19.8% were currently smoking. Despite the reported good self-related health status (74.4%) and high cognitive functionality (94.1%) of the older men, only 7.9% sought medical care outside of experiencing illnesses. Thirty-seven percent of rural participants sought medical care when they were ill compared with 31.9% of their urban counterparts. Thirty-four percent of the participants took the medication as prescribed by the medical doctor; 43% self-reported being diagnosed with cancers such as prostate and colorectal in the last 6 months, 9.6% with hypertension, 5.3% with heart disease, 5.3% with benign prostatic hyperplasia, 5.3% with diabetes mellitus, and 3.8% with kidney/bladder problems. Approximately 14% and 24% of the participants indicated that they were unaware of the signs and symptoms of hypertension and diabetes mellitus, respectively. The elderly men displayed low health literacy and poor health-seeking behavior. These findings can be used to guide the formulation of health policies and intervention programs for elderly men in Jamaica.

Public and private health care utilization differences between socioeconomic strata in Jamaica.

OBJECTIVE: To assess trends in the use of private and public health care services among Jamaicans over a 15-year period (1991-2007). DESIGN AND METHODS: Statistics on the use of health care services were taken from the Jamaica Survey of Living Conditions (JSLC) for the 15-year period 1993 to 2007. Use of hospital services were represented in income quintiles and compared for private and public facilities. The difference in percentage use between public and private was compared by quintiles over the period and the variability in those differentials assessed. RESULTS: This study highlights the increasing use of private services by increasing wealth, exaggerated for the wealthiest quintile. There is a widening of the differences in utilization between public and private centers as income level increases (P < 0.001). CONCLUSIONS: Internal and external economic conditions influence the use of private and public health care services in Jamaica. Although the relative increase in the cost (to the user) of public health care is more than that for private health care, the actual cost to use the public health care system is still significantly cheaper than using the private system. Lower income health care users tend to take the lesser cost option.
