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.

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,

occasions (green: 6‐10, orange: 11‐15; grey: 16‐20; red: 21+) A further important problem is that alcohol is often consumed
along a binge drinking pattern (i.e. high intake on few occasions).
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).

Comments
Fish, unpolished rice and sugared tea continue to be the staple
diet in Seychelles. 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.

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.
