National Survey of Noncommunicable Diseases in Seychelles 2013‐2014 (Seychelles Heart Study IV): main findings This report focuses on selected main findings from the 2013 National NCD Survey and these findings are compared, whenever possible, with results from previous national NCD surveys in 1989, 1994 and 2004. A technical report presenting crude results for all the variables assessed in the 2013 NCD survey entitled “National Survey of Noncommunicable Diseases in Seychelles 2013‐2014 (Seychelles Heart Study IV): Methods and Overall Findings” was produced by the Public Health Authority, Ministry of Health, Seychelles (2nd version, 10 November 2014). These findings were discussed in two half‐day meetings in the presence of Minister of Health, officials and interested persons on 31 October & 4 November 2014. Detailed analysis of specific issues and related recommendations will be available in separate reports. Public Health Authority 24 February 2015 (version 2)

The key information needed to guide interventions for NCD Main risk factors of NCDs prevention and control is the current levels of risk factors in the population. Population‐based surveys require that participants The focus on 4 main modifiable behaviors to reduce the NCD are randomly selected from the general population. Previous burden is encapsulated in the so called “4*4 strategy”, advocated population‐based surveys of NCD risk factors were conducted in in the Political Declaration on NCD Prevention and Control 1989, 1994 and 2004.

The survey was performed in a sex and age stratified random Participants with a newly found abnormal medical condition sample of all adults aged 25‐64 years of Seychelles between received a referral form signed by the doctor of the survey (a October and December 2013 on Mahé and during 2 weeks in copy of which is kept at UPCCD) and were advised to go to a February 2014 in the islands of Praslin and La Digue.

Number of drinks on a typical Friday (orange: 3; grey: 4; red: 5‐10: blue grey: 11‐20) The prevalence of heavy drinkers (≥5 drinks per day on average), which was high in men in early surveys (1989, 1004) has decreased over time but is still substantial (nearly 11% of men in 2013). However, the prevalence of both moderate drinkers (1‐2 drinks per day) and marked drinkers (3‐5 drinks per day) has increased over time in both men and women. Of note, alcohol intake was not assessed in 1994 for persons drinking less than once weekly and the prevalence of category 1‐ 25 ml/day is underestimated in 1994.

Alcohol consumption was not assessed in 1994 for persons drinking alcohol less often than once weekly, hence the frequency of drinking 1‐25 ml/day is under‐estimated and the category of 0 ml/day is overestimated in 1994.

Number of days drinking more than 4 (women) or 5 (men) red: 5‐10: blue grey: 11‐20) drinks per month (orange: 5‐10; grey: 11‐15; red: 16+) Around 20% of all adults drink vey high amounts of alcohol on Few adults drink on workdays but high proportions drink on more than 5 days per month and around 10% of all adults drink Fridays and Sundays with even higher proportions drinking on excessive alcohol amounts of alcohol on more than 10 days per Saturdays. This suggests binge drinking patterns in many month. Binge drinking is more frequent in male vs. female and in drinkers. persons of lower vs. higher SES. There was little difference between young and older persons. Overall, these figures show Figure 9. Proportion of persons drinking homebrews (kalou, baka, high frequency of binge drinking, with many men and women lapire) among 665 current drinkers (yes: blue) drinking in excess on many days per month. Comments Ethanol consumption per capita decreased over the past 25 years, largely driven by both a marked decrease of heavy drinking among men and a largely decreasing consumption of homebrews between 1989 and 2013. However, while the prevalence of heavy drinking (>5 drinks per day on average) has decreased, the frequency of light and moderate drinking has increased among both men and women. Because the population has largely increased, the total numbers of heavy drinkers in the population (mainly men) remains high, and the numbers of drinkers of 1‐2 and 3‐5 drinks per day on Homebrew drinking was very low in 2013, and was higher in male average have largely increased. This implies large and further vs. female, older vs. young, and lower vs. higher SES persons. increasing numbers of health, social and other alcohol‐related Figure 10.

Binge drinking (as compared to regular low intake) is associated with many health and social problems (heart attack, drunk driving, violence, etc). Findings in the different surveys between 1989 and 2013 confirm that alcohol misuse remains a main public health issue in Seychelles and requires a strengthened public health response, e.g. frequent random alcohol checks of all drivers in sensitive points (discotheques, social gatherings at night, etc), high taxes on alcohol beverages on a basis of alcohol content of beverages, severe penalties for drunk driving, ban on advertisements of alcohol beverages in public mass media, awareness campaigns, etc). Around 20% of all adults report drinking >10 drinks on single special occasions. This proportion is higher in male vs. female, The WHO member states, inclusive Seychelles, have agreed on a young vs. old, and lower vs. higher SES persons.

Of note, these items do not include a number of nutrients so the trends towards a more diverse diet are welcome to provide healthy micronutrients and vitamins. A few other items are consumed frequently in 2013, e.g. bread, vegetables, fruit, lentils, breakfast cereals, milk, and cheese. Intakes of meat, processed meat, potatoes, potato chips, and pasta are still low (although likely largely increased compared to past years). Consumption of poultry is more frequent. Intake of salted and sweet snacks is substantial. The data do not provide information on portion sizes. Therefore The proportion of people reporting paying attention to salt high frequency of eating an item per week (e.g. “vegetables”) reduction (a main measure for reducing blood pressure) is high in does not necessarily mean that a product is consumed in large the population, likely reflecting ongoing awareness campaigns on amounts.

Overall, a more varied diet, as found in the 2013 survey, has Figure 9. Took vitamins during last 4 weeks (red: yes) advantages in providing a broader range of nutrients and vitamins (e.g. bread, cheese, milk, breakfast cereals,) which are not present in rice and fish. However, the current diet also includes substantial intake of nutrient poor and energy rich food items (e.g. large amounts of sugar added in tea/coffee, soft drinks, juices in packets, salted and sweet snacks, processed meat, etc). These nutrients contribute large amounts of sugar, salt, saturated fats or trans fats, which are main causes of cardiovascular disease. Sugared drinks have little nutritional value and contribute large energy intake and, therefore, fuel the raising prevalence of obesity. There is a need to sustain health education campaigns on healthy nutrition, e.g. emphasizing on five portions of vegetables and (fresh) fruit a day, need to prefer water (including tap water), The proportion of adults taking vitamins is high, possibly semi‐skimmed milk and fresh fruit juices to soft drinks of packets reflecting health concerns.
