Abstract
Objective: The purpose of this study is to examine secular
trends in the occurrence of type 2 diabetes in community-dwelling
Trinidadian subjects.
Methods and design: We selected two regions in Trinidad and
identifed communities where people both live and seek health care
services. We used several defnitions of type 2 diabetes to recruit
participants. Data on age, gender, onset of illness and educational
level as a marker of socioeconomic status was collected.
Findings: 301 participants were entered into the study. There was
ethnic disparity but a reversal from South East to Africans. A strong
inverse linear relationship (Pearson’s coeffcient r=-0.82, p ≤ 0.05)
was found between BMI and age at diabetes onset. Between the
1990’s and 2004-2014 in two regions of Trinidad the number of
patients with T2DM doubled, occurring more commonly among
females, the obese and overweight, a tendency towards younger
age groups and those of lower socioeconomic status (SES).
Conclusion: We provide evidence that at the community level
that the occurrence of T2DM is increasing, and shifting towards
younger age groups.
and quantifying the number of people afected, now and in the future,
is important to allow for rational planning, allocation of resources and
efective strategies for prevention and management [4]. In addition
comprehensive and up-to-date survey data at the community level
helps to identify potential gaps in care, and to monitor and evaluate
the provision of treatment to patients in the most efcient manner.
Te purpose of this study is to examine secular trends in the
occurrence of type 2 diabetes in community-dwelling Trinidadian
subjects.
Methods
We used a cross sectional study design. Te population
consisted of all adult patients (>18 years) with T2DM, residing in
the community and receiving care at the main primary health
care facility (PHCF) serving that community. In Trinidad there
are four Regional Health Authorities (RHA) that deliver care to
well demarcated communities. Te communities chosen for this
study came from two of these RHA, the North-Central RHA and
the Eastern RHA. Te two main PHCF serving these communities
were selected for the conduct of the study. Te starting point was
the identifcation of all patients who met the criteria for T2DM. We
defned T2DM as a physician diagnosis as well as satisfying the WHO
criteria i.e. – a fasting plasma glucose ≥ 7.0mmol/l (126mg/dl) or 2–h
plasma glucose ≥ 11.1mmol/l (200mg/dl), or an HbA1c of >7%. [4].
Patients who met these criteria were invited to participate in the
study. All patients with gestational diabetes or type 1 diabetes were
excluded from the study. All data were collected using a specifcally
designed data collection instrument, which include demographic
data, i.e. age, gender, ethnicity, body mass index (BMI), education
level and treatment. Body mass index (BMI) was based on measured
height and weight on physical examination. BMI is computed as
weight in kilograms divided by height in meters squared (kg/m
2
).
BMI was defned according to standard methods, normal (less than
25), overweight (25–29.99) and obese (30 or greater) [5]. Educational
level was classifed into fve categories based on access to education
in Trinidad. All data was stored, retrieved and analyzed using SPSS
version 22. A p ≤ 0.05 was considered signifcant. Ethical approval for
this study was obtained from the Ethics Committee of the University
West Indies St Augustine.
Introduction
Type 2 diabetes (T2DM) is a global public health crisis that
threatens the economies of all nations, particularly developing
countries. Fueled by rapid urbanization, population growth,
increasing life expectancy, nutrition transition, and increasingly
sedentary lifestyles, the epidemic has grown in parallel with the
worldwide rise in obesity in both adults and adolescents. [1,2]. Te
burden of type 2 diabetes and its complications, including macro- and
microvascular complications, are increasingly recognized as a global
health priority. Te estimated prevalence of diabetes in Trinidad
reported by the International Diabetes Federation is 13.9% [3], one
of the highest in the region of the Americas, with the total number
of cases (20-79) years at 2013, being 132 340. Te mean health care
expenditure per person with diabetes is estimated at $1212 (USD).
