Background
Bereavement is an established risk factor for morbidity and mortality which has received little attention in prevention research. It is defined as the fact of the death and is different from the concept of grief. Grief is an emotional response such as sorrow, sadness, or anger. Exposure to bereavement within one’s social network is associated with a 2- to 5-fold increased mortality risk which can persist for as much as 10 years [
1,
2]. This exposure is also associated with increased rates of health care consumption [
3,
4]. Anecdotes describing the behaviors of bereaved people include references to changes in patterns of sleeping and eating. The detrimental version of these behaviors includes insomnia and overeating. The emergence of new, detrimental behaviors after exposure to bereavement may be a mechanism driving the downstream increases in health care consumption. The existing literature describing alcohol use behaviors shows conflicting patterns of protection and injury. Social drinking protections cognition [
5]. Bingeing or heavy drinking increases illness and premature mortality risk [
6,
7]. This report examines the co-occurrence of bereavement and binge drinking to answer a single question. Is binge drinking significantly more common among persons with new bereavement?
Bereavement related health effects extend beyond biological relatives to encompass coworkers and others with strong social ties, i.e., fictive kin [
8,
9]. The strongest evidence for these effects comes from cohort studies. Longitudinal analyses of cohorts show bereavement is associated with a 2-fold increased risk of death in the 6 years following the event [
1]. In these cohorts, rates of detrimental health behaviors - insomnia, smoking, and alcohol use – were also elevated among the bereaved [
9,
10,
11]. These observations suggest bereavement has its pervasive and long-lasting effect through behavior change. Can this perspective be extended beyond families to the population level? There is evidence that the numbers of persons exposed to bereavement are increasing. Population growth has combined with later age at death to increase the annual number of deaths. In the United States, this annual growth in numbers of deaths has been observed each year between 1935 and 2010. In 2010, there were almost 2.5 million deaths. By 2018, this number had increased to 2.8 million [
12]. Recent work has provided an estimate for numbers of bereaved linked to a single death from a single cause - COVID. With COVID, an estimated 9 persons are in the social network of the decedent [
13]. Cohort studies, population growth, and cause of death analyses provide indirect evidence for greater numbers of persons with exposure to bereavement. Is there a parallel trend of emerging, detrimental health behavior over the same 75 years? Answering this question requires a dataset with bereavement exposure combined with health behaviors. Currently, no complex sampling survey connects bereavement and health behavior.
Complex sampling surveys routinely assess health behaviors. The Behavioral Risk Factor Surveillance Survey (BRFSS) has more than 30 years of population-level health behavior assessment. The types of behaviors BRFSS includes changes over time to meet current public health concerns. For example, alcohol use only became a regular part of BRFSS in the early 2000s [
14]. Bereavement exposure not routinely assessed in BRFSS. Currently, exposure to bereavement is indirectly inferred from big data sources - population registries or complex sampling surveys of death certificates. [
2,
3,
15]. National mortality registries are a comprehensive listing of deaths. These sources have been used to link bereavement to health care consumption by family members [
3]. The National Mortality Follow Back Survey (NMFS) is a complex sampling survey designed to validate death certificates and ascertain events surrounding decedent health prior to their death. NMFS data are derived from interviews with family members. Despite the sensitive nature of the topic, participation rates range from 90 to 95 % in the 3 cycles of NMFS – 1966, 1986, and 1993. NMFS does not have health behavior for the informant. The Health and Retirement Survey (HRS) is a longitudinal cohort [
16]. Health outcomes – not behaviors – are the focus of HRS reports. HRS-based analyses have identified mediators and moderators of health care consumption after bereavement [
1,
4,
9,
10]. The concept of mastery – global, health, and financial – is a composite attitude index that is linked to probability of health care encounters such as doctor visits and overnight hospital stays [
10]. Timing of exposure to bereavement in HRS is not precisely characterized well enough to test hypotheses regarding behavior change. HRS captures all deaths occurring in childhood through the ones occurring between waves of interviews for adults aged 50 years and older. To ascertain changing health behaviors, the timing of exposure and behavior needs temporal standardization. Existing registry or NMFS data also has limited potential for mechanistic studies because each is missing informant health behaviors.
Alcohol consumption and abuse is a well-studied health behavior. Binge drinking and its association with bereavement is a new area of study for population health [
11,
17]. Bingeing is a global issue with rates that vary across nations, ranging from 12.6 % (Singapore) to 40.4 % (Mexico) [
18,
19]. Binge drinking is part of a larger spectrum of excess alcohol use. According to the Centers for Disease Control and Prevention, in the U.S. excess alcohol use costs
$28 billion in health care,
$179 billion in workplace productivity,
$13 billion in automobile accidents, and
$25 billion in criminal justice. These reports indicate that reductions in detrimental consumption could have a large positive effect on a broad spectrum of outcomes – not just health [
3,
20]. In the United States, annual cross-sectional surveys show increasing rates of bingeing between 2011 and 2017 from 16.7 % 18.0 % [
21]. Rates also vary by state and region in the U.S., with rates highest in the Midwest region (20.0 %) and in small metropolitan areas (17.7 %) [
22]. Between 2011 and 2014, the state of Georgia (southeastern region) had bingeing rates between 13.1 % and 16.6 %. Traditional studies of bingeing focus on age at first use and its contribution to subsequent heavy drinking [
23,
24]. While the prevalence of bingeing is well-documented, less is known about the individual, social, and contextual factors that initiate bingeing [
25,
26]. The pervasiveness of binge drinking creates an ideal starting place for a study of health behavior change as a mechanism for bereavement-related injury.
Before the COVID-19 pandemic, the U.S. state of Georgia began field testing an item estimating the prevalence of new bereavement in the years 2018 and 2019 with the question
Have you experienced the death of a family member or friend in the years 2018 or 2019? The prevalence of bereavement for that period was 45.8 % in a population of 8,164,018 adults aged 18 years and older [
27]. Georgia BRFSS contains the necessary elements to study co-occurrence of binge drinking and bereavement. Its population-level design creates an opportunity to measure the scale of bereavement and behavior change.
Discussion
The hypothesis guiding the aim of this investigation is that bereavement increases the likelihood of high-risk alcohol consumption. This inference is based on prior studies of bereavement-related behaviors. Our results provide additional support for this hypothesis. The inclusion of bereavement in an annual prevalence survey is new. However, a cross sectional survey like BRFSS cannot be used to establish a causal relationship. Its addition provides opportunity for surveillance. Surveillance is the rationale for conducting surveys like BRFSS. Emerging threats to the population health can be identified with surveillance. Monitoring patterns of alcohol use show a clear trend in binge drinking. By adding new bereavement, a potential trigger for bingeing is identified. Repeated measurement of new bereavement in future annual surveys is needed to provide evidence that co-occurrence is a trend requiring public health attention.
Gaps remain in our understanding of the association between new bereavement and binge drinking. Data in these analyses are subject to limitations that include recall bias, missing responses, and the extraordinary historical events occurring since the survey in 2019. There are traditional methods available to evaluate limitations like recall bias and missing responses. Sources of recall bias can be better understood with a targeted study of death certificates. The design of the National Mortality Follow Back Survey can be modified for this purpose. The bereavement item is new. All new BRFSS items are placed at the end of the interview session. The rate of missing responses is largely due to random dropouts at points prior to the bereavement item. Rates of bereavement in this report are calculated using multiple imputation combined with complex sampling weights. This approach was particularly valuable because there are no other points of reference. Repeated assessment of new bereavement in future surveys will give us additional rates for comparison. The bereavement item also needs to be included in BRFSS from other states to provide additional reference points. Work is underway to support a nationwide effort. The extraordinary historical event – a global pandemic of COVID19 -occurred after this survey was completed. It is reasonable to assume that the pandemic will have an outsized influence on rates of new bereavement as well as rates of binge drinking. Other than increased rates, the biases created by history will become evident over time. This is one more reason for repeated surveillance for new bereavement. Bereavement due to the pandemic, climate change related mortality, and war increases the salience of measuring bereavement in complex sampling surveys like BRFSS.
Despite these limitations, this report shows the co-occurrence of bereavement and bingeing at a rate greater than would be expected by chance alone. New bereavement is a feature of the human condition. While increased in life expectancy is a welcomed public health achievement, the risk of bereavement increases across the life course. The deaths of parents and older relatives is happening with increasing intensity in countries where there are large number of older adults. The growth of an aging population and their associated deaths was our initial rationale for examining bereavement and its relationship to mortality [
1], health care utilization [
4], and insomnia [
9]. We also examined health mastery and its contribution to resistance of negative health effects [
10]. A rationale for the present study is the nagging question of mechanism. How does bereavement lead to negative health? In population-based work, mechanism requires greater precision in defining a time frame both the exposure (bereavement) and the behavior (alcohol consumption). The BRFSS items reference an intentional period for the exposure – 24 months before the interview and a period for health behaviors – the 30 days before the interview. To put it succinctly, do high-risk behaviors occur in the 30 days before interview? Is the prevalence of these behaviors significantly greater among the newly bereaved? There are hints that multiple high risk health behaviors are increased by bereavement. These additional high-risk behaviors include smoking plus poor physical and mental health. Bereavement care that includes attention to alcohol use may also have a positive impact on other negative health behaviors and influence multiple mechanisms driving individual-level morbidity and mortality after bereavement [
32].
Alcohol use literature contains paradoxical reports of both protective and detrimental effects. This conflict between protective and detrimental effects complicates interpretation of the opposing age and gender trends for bingeing and social drinking observed in this report. Moderate or social drinking is defined as 7 or fewer drinks in a 7-day period. The oldest age category (65 years and older) and females have the highest rates of social drinking. These two groups also have the highest rates of new bereavement – 65 years and older (50%) and women (46%). Analyses of this paradox is out of the scope of this report. However, one paradox is the literature promoting moderate alcohol use as a protective effect for cognitive function among older adults [
5]. This is directly opposite to the literature describing the fall risk associated with alcohol use [
6]. Another paradox is the framing of alcohol use as both an exposure and an outcome for individual health. Several reports provide evidence that excess drinking increases risk of pre-mature mortality [
7]. Young adults and males are at highest risk for this outcome. There is an emerging literature providing evidence that bereaved males of all ages are more vulnerable to hazardous drinking, dependence symptoms, and harmful use [
11]. Our results suggest that screening for bereavement is likely to identify persons with harmful patterns of drinking – an improvement over screening for alcohol use alone.
The complexity of these contradictions is further muddied by variations in individual biology and cultural norms. Alcohol metabolism varies across individuals and populations [
33]. This variability influences clinical and public health definitions of abuse and the manifestation of negative effects. There is a long history of cultural norms and expectations for bereavement related behavior that can initiate or exacerbate use of alcohol. In western cultures, funerary rites explicitly include alcohol consumption [
34]. This expectation is present in cultures worldwide [
35,
36]. These paradoxes require evaluation and refinement to support the development of population-level interventions to diminish bereavement-related alcohol injury.
What has this report added to our public health perspective on bereavement and binge drinking? Where do gaps remain? There is extensive evidence for poor mental health after the death of friends and family [
3,
8,
10]. The evidence that bereavement could act to increase risk of binge drinking is an advance in public health perspectives on mechanisms driving health behavior change. With this simple idea, future research can measure and target the co-occurrence of bereavement with detrimental alcohol use. This approach can be applied at multiple levels ranging from a global perspective to something very localized. The World Health Organization, Centers for Disease Control and Prevention, and the Georgia Department of Public Health already have existing strategies for reduction of bingeing. There are other alcohol control related policies being evaluated in 194 countries [
17]. Sales restrictions were the most common policy implemented across geopolitical blocs. These policies are also consistent with the SAFER initiative – Strengthen restriction, Advance drink driving counter measures, facilitate access to screening, interventions, and treatment, enforce bans or comprehensive restrictions on alcohol sales and raise prices on alcohol through excise taxes or pricing policies (
https://www.who.int/initiative/SAFER). Target 3.5 of Health-related Sustainable Development Goals (SDG) calls for nations to strengthen the prevention of harmful use of alcohol. On a country- or state-level, measuring alcohol outlet density and implementing unit pricing / alcohol taxes is a strategy. This approach demonstrated effectiveness after the global financial crises of 2008 in the United Kingdom [
37]. Alcohol control policies increase its price or place limits on amounts for household purchase through a Minimum Unit Pricing policy were effective without being burdensome or resorting to extremes like prohibition [
37]. Responding to widespread bereavement may be a path towards the goal of sustainable prevention in harmful use of alcohol [
38]. Screening for new bereavement can serve to initiate action at all levels of health care.
