Abstract

Introduction and aims

There are significant gender differences in alcohol consumption throughout the world. Here we report the results of an alcohol consumption survey on the rural island of Savaii, in the Pacific nation of Samoa.

Design and methods

Eleven villages were selected for sampling using a randomized stratified cluster sampling methodology. A total of 1049 inhabitants over the age of 40 years (485 males and 564 females) were surveyed about alcohol consumption over the past year, and a 72.2% participation rate was achieved.

Results

A significant gender difference in alcohol consumption was found: 97.3% of women and 59.4% of men reported no alcohol consumption over the past year. This is one of the most significant gender differences in alcohol consumption in the world. No significant difference between genders was seen in those who consume only 1–5 alcoholic drinks per week (P = 0.8454). However, significantly more males than females consumed 6–25 drinks per week (P < 0.0001), 26–75 drinks per week (P < 0.0001), and 75+ drinks per week (P < 0.0001).

Discussion and conclusion

This extreme gender difference in alcohol consumption is attributed to several factors, both general (alcoholic metabolism rates, risk-taking behaviors, general cultural taboos, etc) and specific to Samoa (church influence, financial disempowerment, and Samoan gender roles).

Introduction

Alcohol-related morbidity and mortality account for a greater global health burden than tobacco products.Citation1 It has been consistently shown through epidemiological studies that men tend to drink more, and more regularly, than women worldwide.Citation2 Several reasons have been given for this near universal trait. Possible biological explanations for the alcohol consumption gender gap include evidence of a lower rate of the gastric metabolism of alcohol in females,Citation3 smaller volumes of body water in which alcohol is distributed in females,Citation4 and a higher likelihood of women experiencing hangover symptoms.Citation5 Cultural explanations include a perception of drinking as a demonstration of masculinity and strength, social sanctions, or stigmas against alcohol consumption by women, higher levels of impulsivity and risk-taking in men, beliefs about the association between drinking and female promiscuity, and a tendency for men to use alcohol as a coping mechanism while women tend to use communication for that purpose.Citation6

Alcohol consumption rates among women are on the rise worldwide, especially in Australia.Citation7 It is hypothesized that as women achieve more in terms of education, social status, and economic independence, cultural restraints on alcohol consumption decrease, and there is a convergence of male and female drinking patterns.Citation8

While evidence of a genetic propensity to alcoholism in Polynesians has been reported,Citation9 comparatively few studies have investigated the epidemiology of alcohol consumption in Pacific populations. This lack of data is compounded by the inappropriate inclusion of Pacific populations with disparate populations of greater numbers. For example, in the United States, epidemiological data are often collected under the group “Asian and Pacific Islander”.Citation10 Such “lumping” of groups with significantly different cultures and ethnicities obscures the higher rates of alcohol consumption among Pacific Islanders, as their numbers are much lower than Asians in the United States, yet their alcohol consumption tends to be higher.Citation11

Some notable studies have helped fill in the gaps of knowledge in Pacific alcohol consumption. Using alcohol sales and production figures rather than epidemiological surveys, McDonald and colleagues concluded that the per capita consumption of alcohol in Pacific nations such as Fiji, Samoa, and Tonga was significantly less than in nearby Australia and New Zealand. However, while a higher percentage of people in the Pacific abstain from alcohol, those who do not abstain tend to consume more, on average, than their counterparts in Australia or New Zealand.Citation12 This pattern was also found in Pacific populations living in New Zealand.Citation13

The independent nation of Samoa, formerly known as Western Samoa, is a relatively underdeveloped Pacific island nation located approximately halfway between Hawaii and New Zealand (). Samoa’s economy is primarily agricultural, with approximately 85% of all adults working solely in local subsistence farming and fishing. The total population in 2001 was approximately 175,000,Citation14 divided between two main islands, Upolu and Savaii. The island of Upolu boasts the majority of the nation’s population (~135,000), as well as the capital city and a more modern lifestyle and economy, as residents of the expanding urban villages gain wage-based employment. While only 20 km of ocean separate Savaii from Upolu, the island of Savaii is much less populated (~42,000) and is among the least modernized regions of Polynesia with an economy almost entirely based on traditional Samoan agriculture and reef fishing, although a nascent tourist trade has been recently established. On Savaii, a traditional village form of government, based on a council of chiefs and local rule, is firmly in place.Citation15

Alcohol was first introduced to Samoa in the 19th century by European whalers and beachcombers. For many decades consumption was kept rather modest due to missionary efforts and lack of supply. A major increase in alcohol consumption came in the 1940s with the influx of over 10,000 American soldiers on Upolu. In the 1970s, Western Samoa Breweries was established, supplying the nation with its first and only nationally brewed beer, Vailima, whose slogan printed on every bottle is “Samoa’s very own beer”.Citation16

Methods

In July 2009, a team of medical students, eye care professionals, and American Peace Corps volunteers provided eye exams and vision screenings for 1049 people in 11 villages on the rural island of Savaii, Samoa (population ~42,000), using a randomized stratified cluster sampling methodology when choosing villages. All villagers 40 years of age or older were invited to participate, and a 72.2% participation rate was achieved across 11 villages. In addition to eye exams, demographic data were collected via questionnaire in the Samoan language, including the questions “Have you had any alcoholic drink in the last year?” and “How many drinks do you usually have in a week”. Standard drinks were explained to participants to be any drink containing 14 g of pure alcohol (355 mL of beer, 150 mL of wine, 45 mL of hard liquor).

This study was approved by the institutional review boards of the University of Hawaii and the Samoan Ministry of Health. Informed consent was obtained from all participants, and the guidelines of the Declaration of Helsinki were adhered to. All data collected were nonidentifiable.

Results

Results of the Savaii alcohol consumption survey are shown in . Of 564 females surveyed, 549 reported abstaining from all alcohol in the past year (97.3%), while 288 out of 485 males (59.4%) reported abstaining from all alcohol in the past year. The mean age of abstaining females (56.7 years) was significantly older, by Student’s t-test, than nonabstaining females (50.8 years) (P = 0.038). The mean age of abstaining males (61.3 years) was significantly older than nonabstaining males (55.8 years) (P < 0.0001).

No significant difference, by Student’s t-test, between genders was seen in those who consume only 1–5 alcoholic drinks per week (P = 0.8454). However significantly more males than females consumed 6–25 drinks per week (P < 0.0001), 26–75 drinks per week (P < 0.0001), and 75+ drinks per week (P < 0.0001).

Discussion

The gender difference in alcohol consumption in rural Samoa is striking. While only 2.7% of women over 40 report consumption of alcohol in the past year, 40.6% of men report alcohol consumption. While some of the significantly low drinking rates in rural Samoan women may be ascribed to the older age of the sample population (over 40 years), these rates must also be considered in the context of the Pacific region, where female alcohol consumption rates are some of the lowest in the world (). Indeed, six of the top 10 nations for female alcohol abstinence in are Pacific nations (Fiji, Samoa, Marshall Islands, Kiribati, Micronesia, and American Samoa). The rurality of the Pacific may play a significant role in this. Previous reports have suggested that alcohol consumption rates among Samoan women rise significantly from rural to urban SamoaCitation17 and from Independent Samoa to American Samoa to Samoans living in Hawaii.Citation18 Although these studies are limited by small sample sizes, they posit that the reported rise in women’s drinking correlates to the increase in the cash economy and Western lifestyle available in the more urban settings of Hawaii and American Samoa. This is in keeping with Neve’sCitation8 hypothesis that as women achieve more in terms of education, social status, and economic independence, cultural restraints on alcohol consumption decrease and male/female alcohol consumption patterns converge.

Table 2 Gender differences in alcohol consumption worldwide

In addition to the factors already discussed for a gender gap in alcohol consumption, we posit certain cultural factors that are specific for rural Samoa. In rural Samoa, women tend to be financially disempowered. Money received by women through commerce, employment, or remittance must often be given to the chief (matai) of the family (usually male). This arrangement strongly discourages alcohol purchase by women.

Within the Samoan cultural framework, there exist numerous women’s groups whose purpose revolves mainly around their roles in the family, village, and church. Among other responsibilities, these groups ensure gathering places where women can come together and bond/discuss shared experiences in a male-free environment. Alcohol plays no role in these female gatherings. On the other hand, alcohol plays a major role in bringing the Samoan males together. Before European contact, Samoan men ingested kava, a traditional drink prepared from the root of the kava plant (Piper methysticum) found among many Polynesian cultures. Kava was ingested at traditional male gatherings, such as chiefly meetings, and has a mild analgesic effect, similar to that of alcohol.Citation19 The traditional gender gap in kava consumption may help to drive the modern gender gap of alcohol consumption.

The traditional cultural landscape of Savaii, Samoa, offers a convenient baseline in which to investigate the social and cultural changes that come with Westernization. Here we offer a baseline for the rate of rural Samoan alcohol consumption as well as explanations, both general and specific to Samoa, of the role of gender in that rate. This information can be used to target alcohol awareness campaigns to those most at risk (males). Valuable future research towards this end would be to conduct a similar assessment of alcohol use in the semi-urban capital of Apia, Samoa. The adoption of a more Western lifestyle in Apia may suggest a different relationship between gender and alcohol.
