Prevalence of mental illness among women in an urban slum area of Jaipur: A cross- sectional study

Gender has been described as a critical determinant of mental health and mental illness. Depression is not only the most common women's mental health problem, but may be more persistent in women than men.To assess the burden of depression, anxiety and stress among women residing in urban slums of Jaipur and also to assess the factors affecting them. A community based cross-sectional study was conducted in an urban field practice area among women aged 18-59 years with calculated sample size of 503. Depression Anxiety Stress Scale (DASS)-21 questionnaire was used to capture the primary outcomes—depression, anxiety, and stress. Data was analyzed using SPSS and MS Excel. The statistical significance was evaluated at 95% confidence level. The difference in proportions was compared using Chi-square test and p-value <0.05 was considered significant. In our study, the overall, the prevalence of anxiety, stress and depression was 38.22%, 9.11%, and 18.61%, respectively which ranged from mild to extremely severe. There were meaningful correlations between probable factors like physical inactivity, poor sleep and generalized pain and DASS scores obtained by the participants. The study showed that the prevalence of anxiety was higher compared to other DASS symptoms. The DASS symptoms were poorly associated to demographic characteristics of the study participants although amongst the separated and widowed females there was significant statistical association.

Expected length of stay at residential aged care facilities in Australia: current and future

This study explores the changing patterns of the length of stay (LOS) at Australian residential aged care facilities during 2008–2018 and likely trends up to 2040. The expected LOS was estimated via the hazard function of exiting from such a facility and its heterogeneity by residents’ sociodemographic characteristics using an improved Cox regression model. Data were sourced from the Australian Institute of Health and Welfare. In-sample modelling results reveal that the estimated LOS differed by age (in general, shorter for older groups), marital status (longer for the widowed) and sex (longer for females). In addition, the estimated LOS increased slowly from 2008–2009 to 2016–2017 but declined steadily thereafter. Out-of-sample predictions suggest that the declining trend of the estimated LOS will continue until 2040 and that the longest LOS (approximately 37 months) will be observed among widowed females aged 50–79 years. Relative uncertainty measures are provided. The results portray the current changing landscape and the future trend of residential aged care use in Australia, which can inform the development of optimised residential aged care policies to support ageing Australians more effectively.

A study of prevalence and comparison of anxiety and depression among separated, divorced and widowed females in the rural population

Abstract Background: Psychological distress is an important immediate outcome of the death of a spouse or divorce, which may arise because of financial and emotional challenges and can lead to adverse health outcomes with more stress, anxiety, depression, and social isolation than the general population. Methods: Cross-sectional study among separated, divorced, and widowed females from two rural villages. All eligible participants were screened for depression and anxiety using DSM 5 criteria. The severity of depression was assessed using the Hamilton depression rating scale (HDRS) and for anxiety, the Hamilton anxiety scale (HAM-A) was used. Results: Out of 162 women, 30% had mild depression whereas 42% of widow and divorced women had moderate levels of depression but it is in 50% of separated women. Severe and very severe level of depression was in around 20% of widowed and divorced women compared to 16% of separated women. There was no anxiety in around 80% of divorced and widowed women whereas 24.3% of separated women had severe anxiety. On regression analysis, separated women, dependent women, and those with less than two years of duration of separation had higher levels of depression and anxiety. Conclusion: The prevalence of Depression and Anxiety is more common in all three groups. Moderate to severe Depression is around 75% among divorced/separated and widowed females but moderate to severe anxiety was more in separated women compared to widowed women. Dependency and the early phase of widowhood/separation were also important associated factors.

Origin and Outcome of Social Polygyny in the Blue Tit

Classic explanations for polygyny consider habitat, genetic makeup and paternal care, but little attention has been paid to social inertia. We studied facultative social polygyny in a population of Blue Tits Cyanistes caeruleus with a low rate of polygyny (3% of males across 12 years). Occurrence of polygyny was best predicted by social turnover after the disappearance of one or more individuals; habitat quality and individual phenotypic traits were unimportant. Females settled as secondary females with a male and in an area they had previously associated with, indicating a role of familiarity in the formation of polygyny. Females mated to polygynous males received less help feeding nestlings. Reduced paternal care is potentially costly, because these females survived less well than females mated to monogamous males. Reduction in care occurred at both primary and secondary nests although polygynous males rarely divided their care between nests. On any given day during the nestling period, polygynous males were more likely than monogamous males to not feed nestlings at all and – as a consequence – polygynous males provided less care in total than monogamous males. Polygynous males rarely intermingled visits at both nests, suggesting a cost of switching between feeding locations. Both primary and secondary nests had reduced fledging success, even after controlling for variation in habitat quality and paternal care, due to a higher rate of nest failure. Paternity loss was higher at secondary nests, presumably because the secondary female copulated with a previous mate that disappeared. Due to increased paternity loss and reduced fledging success polygynous males did not sire more fledglings than monogamous males in a given season. Thus, the benefit of social polygyny for males seems limited. Social polygyny in our population probably arises as a by-product of widowed females settling as secondary mates with a familiar male or in a familiar area, thereby making the best of a bad situation.

Study on the Utilization of Inpatient Services for Middle-Aged and Elderly Rural Females in Less Developed Regions of China.

The aim of this study is to understand the utilization of inpatient services and its contributing factors among middle-aged and elderly females (MAEF) in less developed rural regions. Five surveys were conducted between 2006 and 2014 with rural residents of Jiangxi by stratified cluster random sampling. Participant females included only those who were aged 45 and above. Complex sampling logistics analysis was performed to analyze the effect of three factors on inpatient service. Complex sampling logistics regression analysis revealed that the probability of hospitalization for the divorced or widowed females was significantly lower than that of married ones (aOR = 0.177, p < 0.05). However, the probability of early discharge was significantly higher among divorced or widowed females than married ones (aOR = 3.237, p < 0.05). In addition, females with chronic diseases were more likely to be hospitalized (aOR = 3.682, p < 0.05). Also, early discharge (aOR = 7.689, p < 0.05) occurred among the participants who should be hospitalized but were not hospitalized occurred (aOR = 3.258, p < 0.05). The continuous improvement of the new rural cooperative medical policy has promoted the utilization of inpatient services for the MAEF. Findings from this study emphasize the need to strengthen the prevention and treatment of chronic diseases among middle-aged and elderly women.

The Association of Pension Income with the Incidence of Type I Obesity among Retired Israelis.

Previous studies have identified obesity and overweight as the fourth leading risk factor for global mortality. The objective of the current study is to investigate gender differences and the impact of wealth and income from pensions, sociodemographic variables, and self-assessment of health conditions on the projected probability to become obese in the postretirement age (67 years and older). We are unaware of previous studies, which explored the direct relationship between obesity, monetary income from pensions, wealth, and self-assessment of health conditions. To conduct this research, we make use of an extensive questionnaire concerning the economic and sociodemographic features and health and housing conditions of individuals administered within the framework of the 2015-2016 longitudinal survey conducted by the Israeli Central Bureau of Statistics (CBS). The survey is representative of the Israeli population and also includes information regarding the weight, height, gender, and age of each household member. Results of our study demonstrate that while for the female respondents older than 67, the projected probability of type I obesity (BMI ≥ 30) drops by 0.41% (p=0.0021) to 0.52% (p=0.0001) with an incremental 10,000 NIS (about $2,500) rise of gross annual income from a pension, for the male respondents above 67 years, the projected probability remains unchanged (p=0.4225). This outcome remains robust even when the 2015 BMI measurement of type I obesity (BMI ≥ 30) is controlled. This drop among women attenuates with a cutoff point increase from BMI ≥ 25 (overweight) to BMI ≥ 30 (type I obesity) to BMI ≥ 35 (type II obesity). Further results indicate that for both genders above 67 years and for men above 62 years, the projected BMI drop of one year decreases with income from a pension (p=0.013, p=0.039, and p=0.007, respectively), although the spread around the projection becomes wider. Compared with other martial status categories, for widowed females, the projected probability of obesity and self-reporting on improved health conditions drops by 6.58% (p=0.0419) to 11.28% (p=0.0048) and 6.55% (p=0.0190) to 7.47% (p=0.0036), respectively. For females older than 67, family status divorced drops the projected probability of obesity by 9.25% (p=0.0319). For males older than 67, results show a rise in projected obesity with car ownership by 6.10% (p=0.0897) to 6.41% (p=0.0469) and a drop in projected obesity with academic degree status by 9.93% (p=0.0106) to 10.14% (p=0.0118) and immigration status from American-European countries by 7.67% (p=0.0821) to 8.99% (p=0.0398) and Asian-African countries by 11.63% (p=0.0245) to 11.99% (p=0.02). Research findings stress the differences and similarities in male-female patterns of obesity after the retirement age of 67 years and may be of assistance to welfare and public health experts.

Transition out of Marriage and its Effects on Health and Health\u2013Related Quality of Life among Females and Males. COURAGE and COURAGE-POLFUS\u2013Population Based Follow-Up Study in Poland

The study explores short-term effects of dissolution of union through divorce/separation and widowhood on physical and mental health as well as health-related quality of life (HRQoL) among females and males in Poland. Considering social selection and social causation theories, the study poses following research questions: are there differences in physical and mental health as well as health-related quality of life that are caused by a marital transition compared to remaining married/cohabiting? Do marital status transitions have different effects concerning physical and mental health and health-related quality of life among females and males? Data for the analysis were available for 1073 people (18+) who participate in the COURAGE-Poland population-based study from 2011 (baseline) and 2015–2016 COURAGE-POLFUS (follow-up). Health status was measured by the WHODAS II and the presence of depression based on the Composite International Diagnostic Interview. Health-related quality of life was assessed by WHOQOL-AGE scale. The analysis has been conducted using the analysis of variance, multinomial logistic regression and generalized liner mixed model according to the dependent variable. Results do suggest that transition out of marriage weakens mental health although the differences in physical health seemed to not be significant compared to the continuously married/cohabiting. The marital dissolution especially causes a decline in the mental health as well as health-related quality of life of males who transitioned to a widowed life. There has not been observed statistically significant change in terms of healthrelated quality of life between first and second wave of the survey among both widowed and divorced males and females.

Gender differences in suicide in Serbia within the period 2011-2015

Background/Aim. The World Health Organisation (WHO) estrimates that approximately 1,000,000 people die by suicide every year. The aim of this study was to examine the gender differences in cases of committed suicides, including suicide rates, socio-demographic factors and methods of suicide in Serbia within the period 2011?2015. This investigation is continuing the previous investigation from the period 2006?2010. Methods. Data were obtained from the Statistical Office of the Republic of Serbia. Their classification related to the suicide method was carried out on the basis of International Classification of Diseases-Tenth Revions- Clinical Modification (ICD-X-CM) (WHO 1992). Statistical analysis was done by using the crude number of committed suicide. Results. Within the period 2011?2015, the total number of suicides in Serbia was 5,897, of which 74.56% were males and 25.44% females (male to female suicide ratio was 2.93). Annual suicide rate (per 100,000) showed constantly decreased from 2011 to 2015, and in 2015 it was 15. Male/female suicide ratio was the highest among adolescents and decreased with age. The suicide was the most often committed by married males (47.6%) and widowed females (38.86%) with completed high school, retired, Serbs. About a quarter (23.38%) suicide committers were older than 75 years, and 39.39% were older than 65 years. The most common suicide method males (64.63%) and females (59.00%) used was hanging, strangulation and suffocation. The second most common method males used was by firearm (18.96%) and females by poisoning (16.73%). Conclusions. Suicide Prevention Programme in Serbia should be primarily oriented towards two age groups at highest risk to commit suicide, towards the adolescents whose suicide was on the rise and towards the elderly male population, less ready to refer to the doctors for help because of problems related to their mental health. With the aim to suicide prevention, doctors should become familiar with community, state and national resources that are concerned with youth and elderly populations, including mental health institutions, family and crisis intervention centers.

Changes in the profile of Australians in 77 residential aged care facilities across New South Wales and the Australian Capital Territory.

Objective Government expenditure on and the number of aged care facilities in Australia have increased consistently since 1995. As a result, a range of aged care policy changes have been implemented. Data on demographics and utilisation are important in determining the effects of policy on residential aged care services. Yet, there are surprisingly few statistical summaries in the peer-reviewed literature on the profile of Australian aged care residents or trends in service utilisation. Therefore, the aim of the present study was to characterise the demographic profile and utilisation of a large cohort of residential aged care residents, including trends over a 3-year period. Methods We collected 3 years of data (2011-14) from 77 residential aged care facilities and assessed trends and differences across five demographic and three service utilisation variables. Results The median age at admission over the 3-year period remained constant at 86 years. There were statistically significant decreases in separations to home (z=2.62, P=0.009) and a 1.35% increase in low care admissions. Widowed females made up the majority (44.75%) of permanent residents, were the oldest and had the longest lengths of stay. One-third of permanent residents had resided in aged care for 3 years or longer. Approximately 30% of residents were not born in Australia. Aboriginal residents made up less than 1% of the studied population, were younger and had shorter stays than non-Aboriginal residents. Conclusion The analyses revealed a clear demographic profile and consistent pattern of utilisation of aged care facilities. There have been several changes in aged care policy over the decades. The analyses outlined herein illustrate how community, health services and public health data can be used to inform policy, monitor progress and assess whether intended policy has had the desired effects on aged care services. What is known about the topic? Characterisation of permanent residents and their utilisation of residential aged care facilities is poorly described in the peer-reviewed literature. Further, publicly available government reports are incomplete or characterised using incomplete methods. What does this paper add? The analyses in the present study revealed a clear demographic profile and consistent pattern of utilisation of aged care facilities. The most significant finding of the study is that one-third of permanent residents had resided in an aged care facility for ≥3 years. These findings add to the overall picture of residential aged care utilisation in Australia. What are the implications for practitioners? The analyses outlined herein illustrate how community, health services and public health data can be utilised to inform policy, monitor progress and assess whether or not intended policy has had the desired effects on aged care services.

Living Alone With Cognitive Impairment.

Although most individuals experiencing cognitive impairment (CI) reside with a caregiver, an estimated 800,000 live alone. Such individuals may have an increased risk for injury to self or others through self-neglect as a result of the CI symptoms. While persons living alone with CI have been identified as an important area for needed research, few studies have been able to examine this population due to the challenges of identifying and recruiting study participants. By using the National Health & Aging Trends Study data set, the researchers explored the characteristics to describe this population. The results of this study indicated that the majority of persons living with CI were older, widowed females who were not diagnosed with Alzheimer's or dementia but tested positive on cognitive screening measures. Further, the majority of persons living alone with CI relied on adult children and paid professionals as the primary care providers.

The biparental care hypothesis for the evolution of monogamy: experimental evidence in an amphibian

Selection for biparental care is considered to be an important factor favoring the evolution of monogamy if the value of exclusive cooperation in care for mutual offspring outweighs the benefits of polygamy for either sex. Support for this hypothesis has come primarily through parent removal experiments in avian taxa. We tested this hypothesis in the first known example of a socially and genetically monogamous amphibian, the mimic poison frog (Ranitomeya imitator). Biparental care in R. imitator is characterized by egg attendance, tadpole transport, and feeding of tadpoles with unfertilized trophic eggs. Using a male removal experiment, we found lower tadpole growth and lower survival for widowed females compared with control families. We demonstrate that in addition to egg attendance and tadpole transport, male parental care is critical for offspring survival throughout larval development. Previous research has shown the importance of female trophic egg provisioning of tadpoles in R. imitator. This, coupled with the results of the present study demonstrating the adaptive value of male care, supports the hypothesis that selection for biparental care has driven the evolution of monogamy in an amphibian.

How do Southern House Wrens Troglodytes aedon musculus achieve polygyny? An experimental approach

I designed two experiments to evaluate how polygyny is achieved in Southern House Wrens (Troglodytes aedon musculus) breeding in a south-temperate population. In the first experiment, I manipulated territory attractiveness by adding high quality nesting sites (nest-boxes) to 50% of monogamous territories (n = 24) and evaluated if males can attract a second female when defending high quality resources. In the second experiment, I simulated high male mortality early in the breeding season by removing 30 territorial males in plots where wrens had been breeding in nest-boxes (n = 47 territories). The first experiment did not induce polygyny: although females switched from breeding in tree cavities to nest-boxes when boxes were erected on their territory, none of the neighbouring females who did not receive a box moved to breed as a secondary female. The male removal experiment did induce polygyny: of 21 experimentally widowed females, 38% bred as secondary females of neighboring males—who expanded their territories in the absence of a defending male—and accepted polygyny even in the presence of neighbouring territories held by bachelor males. Secondary females mated to polygynous males were rarely helped by the male while feeding nestlings, but primary and secondary females overlapped very little in the use of space. Hence, females mated to polygynous males may share parental care disproportionally but not territorial resources. Female attachment to territories and exclusive use of space together with male’s expansion of territories to achieve polygyny suggests that Southern House Wrens engage in sublease polygyny.

Analysis of condom use and its factors on female sex workers in Shandong province

This study was to investigate the condom use and its factors on sex workers in Shandong province, and to provide effective suggestions for AIDS prevention strategies and interventions. From April to July in 2009, 4732 female sex workers were investigated through anonymous questionnaires from 11 cities which were selected based on the AIDS epidemic, geographic location, economic conditions in Shandong province. Serum samples were collected and antibodies were tested by ELISA and TPPA from 4641 people. 4732 female sex workers who were 15 - 58 years old were investigated and the majority belonged to the low age group (≤ 24 years old) which accounted for 61.5% (2912/4732). Among the 4732 female sex workers, the unmarried, the divorced, or the widowed females accounted for 72.8% (3441/4725) and 72.0% (3403/4726) of them were poorly educated.42.3% (1994/4719) of them were found from other provinces. The right answers for knowledge of AIDS accounted for 45.7% (2164/4732). 80.6% (3416/4236) of these females were found to used condoms in the most recent commercial sex activity. The rate of consistently using condoms in sex activity during the last month was 58.4% (2467/4221). In this survey, 7.3% (337/4637) of investigated females had been diagnosed with sexually transmitted diseases, 30.7% (1449/4726) of them had received HIV antibody test, 70.4% (3323/4732) of these people had received the AIDS intervention services, and 3.6% (167/4668) of them had ever used drug. Multivariate logistic regression analysis showed that high education level (junior high school or lower vs senior high school or higher, adjusted OR = 0.77, 95%CI: 0.67 - 0.90), having received the HIV intervention (received vs unreceived, adjusted OR = 1.36, 95%CI: 1.17 - 1.58), antibody detection (done vs not done, adjusted OR = 1.33, 95%CI: 1.15 - 1.55), and good knowledge about AIDS (low score group vs high score group, adjusted OR = 0.37, 95%CI: 0.32 - 0.44) were independent factors that increased safe sex behavior; while using drug (drug vs not drug, adjusted OR = 0.22, 95%CI: 0.15 - 0.31) was a negative factor. The prevalence rate of HIV infection among female sex workers was low in Shandong province. However, the low rate of condom use and the high prevalence of self-reported STD-related symptoms suggested that more attentions should be paid to the factors of risk behaviors, and more targeted interventions are critically needed.

Fitness costs associated with mounting a social immune response

Social immune systems comprise immune defences mounted by individuals for the benefit of others (sensuCotter & Kilner 2010a). Just as with other forms of immunity, mounting a social immune response is expected to be costly but so far these fitness costs are unknown. We measured the costs of social immunity in a sub-social burying beetle, a species in which two or more adults defend a carrion breeding resource for their young by smearing the flesh with antibacterial anal exudates. Our experiments on widowed females reveal that a bacterial challenge to the breeding resource upregulates the antibacterial activity of a female's exudates, and this subsequently reduces her lifetime reproductive success. We suggest that the costliness of social immunity is a source of evolutionary conflict between breeding adults on a carcass, and that the phoretic communities that the beetles transport between carrion may assist the beetle by offsetting these costs.

Socioeconomic risk factors for lung function decline in a general population

The aim of our study was to examine sex-specific associations between different aspects of socioeconomic status (SES) (educational level, occupational status, income) and lung function in a general adult population. In the Hordaland County Cohort Study, 1,644 subjects aged 26-82 yrs at baseline answered questionnaires and performed post-bronchodilator spirometry both in 1996-1997 and in 2003-2006. We performed adjusted linear regression analysis on the effect of SES on decline in forced experimental volume in 1 s (FEV(1)), forced vital capacity (FVC) and FEV(1)/FVC. Mean annual decline in FEV(1) from baseline to follow-up was 57 mL (se 1.3) and 48 mL (se 1.0) for males and females, respectively. Males had a larger decline in FVC than females, while females had a larger decline in FEV(1)/FVC. Lower education and low occupational status were associated with larger male lung function decline. SES did not affect female lung function decline. However, marital status was a significant predictor; unmarried females had less decline than both married and widowed females in both FEV(1) (adjusted mean annual difference 8 mL and 16 mL) and FVC (adjusted mean annual difference 8 mL and 18 mL). Low SES was associated with increased lung function decline in males. For females, marital status was more important.

The Round‐Eared Sengi and the Evolution of Social Monogamy: Factors that Constrain Males to Live with a Single Female

AbstractAnimal dispersion in space and time results from environmental pressures, and affects the outcome of a species’ social organization. When females are solitary, males may either roam or be pair‐living. We studied possible environmental influences affecting the social organization of the round‐eared sengi (Macroscelides proboscideus) in a semi‐desert in South Africa, using trapping and radio‐tracking across 2.5 yr. Adult sex ratios did not deviate from 1:1 and we found no indication of sexual dimorphism in body mass. Females maintained exclusive areas, which had little overlap (&lt;4%) with neighbouring females (NF), and males overlapped predominately only with the home range of single females. Generally, inter‐ and intra‐sexual overlap with neighbouring individuals was low (3–6%) for both sexes, indicating territoriality and pair‐living. Pairs were perennial and territories were maintained year‐round. However, males generally maintained much larger areas than females, which were sensitive to population density. Male space use appeared to be primarily limited by the presence of neighbouring males. Female home ranges were smaller‐sized despite changes in population density, possibly for energetic efficiency. Some paired males attempted to take over widowed females, but shifted back to their original home range following the intrusion of an un‐paired male. We conclude that social monogamy is the predominant social organization in round‐eared sengis in a semi‐desert that may have resulted from females living solitarily in small exclusive territories, balanced sex ratios, and from a low variation of body mass between males.

Life satisfaction in Malawi and the importance of relative consumption, polygamy and religion

AbstractHappiness equations for Malawi are estimated using a new household survey. It is apparent that absolute consumption level is strongly associated with satisfaction. Both objective and subjective relative consumption in the neighbourhood is positively associated with satisfaction. Male satisfaction is associated strongly with relative consumption but female satisfaction is not. Separated or widowed females are less happy than males indicating a vulnerability that acts as a disincentive to leave husbands during marital problems. Polygamous females in traditional religions are less satisfied than other females whilst there is some evidence that male Muslims in polygamous relationships are more satisfied.

Experimental removal of the male parent negatively affects growth and immunocompetence in nestling great tits

Given the available empirical evidence on the benefits and costs associated with immune defence, a role for the immune system in the trade-off between current and future reproduction has been predicted. This hypothesis was studied in a free-living population of great tits (Parus major) by examining the effects of male removal on the immunocompetence, body condition, and recapture probability in the widowed females and their nestlings. Furthermore, we investigated whether growth and its relation to immunocompetence were affected in the nestlings. For a short-lived species such as the great tit, one could predict that widowed females will compensate for the lack of any male assistance in feeding of their chicks and that they consequently might jeopardize their own health. However, we did not find any negative effects of male removal on body mass or condition, nor on humoral immunocompetence against sheep red blood cells in the widowed females by the end of the feeding period. In contrast, we observed significantly reduced body mass and size as well as a reduced T-lymphocyte cell-mediated immune response (expressed as the thickness of the swelling to a subcutaneous injection with phytohemagglutinin) in the experimental nestlings compared to the control nestlings. In addition, the experimental nestlings showed a tendency for a reduced chance to be found breeding the following year. Furthermore, our results showed that in the experimental nestlings, which suffered from unfavourable growth conditions, tarsus length was inversely related to cell-mediated immunocompetence, whereas in control nestlings this relationship was significantly positive. The relationship between cell-mediated immunity and body condition was found to be significantly positive in the experimental nestlings while in control nestlings there was no relationship between both variables. The latter finding suggests different priorities of investment in body condition between different growth conditions.

Time constraints and trade-offs among parental care behaviours: effects of brood size, sex and loss of mate

Animals that provide care to their offspring are likely to face time constraints and, consequently, need to trade-off allocations of time among different behavioural activities. Parental allocation of time is often influenced by intrafamilial conflicts including conflicts of interests between parent and offspring and between parents over optimal parental effort. We investigated effects of offspring demand (by manipulating brood size) and loss of mate (by experimental removal of mate) on allocation of time among parental and nonparental behaviours in the burying beetle Nicrophorus orbicollis. With increasing offspring demand, allocation of time to parental care occurred at the cost of nonparental behaviours. Time allocation among parental care behaviours changed with offspring demand. Time spent on care behaviours from which offspring benefit simultaneously did not change with increasing offspring demand. In contrast, time spent on care behaviours that offspring receive individually increased with increasing brood size. This suggests that costs for parents and benefits for offspring differ considerably among parental care behaviours. Removal of the mate affected males and females differently. Widowed males increased their effort, whereas widowed females showed no change in their effort. This result suggests that males and females negotiate their parental effort differently, and costs and benefits of parental care differ considerably between the sexes. In general, our study shows a plastic parental response to mate loss and simultaneous change in offspring demand, indicating that parents negotiate parental efforts while considering offspring demands.

Health, Widowhood, and Family Support in the North and South Pacific: A Comparative Study

SUMMARY This paper compares the impacts of health and widowhood on the level of support received by elderly women living in small island communities within the Philippines and Fiji. Using a theoretical perspective of ongoing reciprocal exchange as opposed to altruistic support within household economies, this paper reviews the impacts of disability and economic contributions on the level of support an elderly female receives. It is hypothesized that as the health of the widow declines her access to care will also diminish due to an inability to contribute to the household economies of the extended family. This paper extends existing work on health and family support of widowed females in the developing world by performing a cross-national comparative analysis as well as by explicitly testing the assumptions of altruism that are a central assumption of most models of long-term care in underdeveloped nations.
