Type 2 Diabetes (T2DM) is a global public health concern, with the majority of
the patients had inadequate glycemic control. In Basrah, Iraq, one of the factors
affecting glycemic control is low health literacy (HL) level. T2DM patients with
low HL have limited ability to understand and apply the regimen to their diabetes
self-management. Therefore, a simplified diabetes nutrition education (SDNE)
may be required to ensure optimum diabetes care. This study evaluates the
effectiveness of SDNE on glycemic control and other diabetes-related outcomes
in patients with T2DM in Basrah, Iraq.
This study involved three phases based on the Generalized Model for Program
Planning conducted at Faiha Specialized Diabetes, Endocrine, and Metabolism
Centre (FDEMC), in Basrah, Iraq. Phase I was a cross-sectional study that
included 280 participants in determining the factors associated with glycemic
control. The factors included socio-demographic status, medical characteristics,
nutritional status, lifestyle behavior, and HL level. The results from Phase I
informed the content for the Phase II study, which involved developing and
assessing nutrition education materials. The developed nutrition education
materials were assessed for face validity, readability, and acceptability using a
14-item HL Scale and the Suitability Assessment of Materials (SAM) instrument
in 30 participants with T2DM. The experts validated the content of the materials.
The effectiveness of the developed nutrition education materials named SDNE
was evaluated at Phase III using a randomized controlled trial (RCT) on glycemic
control and other diabetes-related outcomes for 22 weeks in patients with T2DM
(n = 208). The assessments were performed at baseline (T0), at 12-week of
intervention (T1), and at 10-week of follow-up (T2). 208 participants were
randomly allocated to either the nutrition education group (NEG, n = 104), or the
control group (CG, n = 104). Those in the NEG received the SDNE curriculum for 12 weeks (12 weekly classes, 1 to 1.5 hours each). Participants in the CG
continued with the usual care.
At Phase I, the participants (N = 151) were at their 50s' with the HbA1c, and HL
scores were 10.0 ± 2.6% and 45.7 ± 24.6. The majority of the participants
(76.4%) had either inadequate (55.7%) or marginal HL (20.7%). Factors
associated with glycemic control included low HL score, low total income, selfemployed,
multiple treatments (oral anti-diabetic drugs and insulin therapy), low
physical activity level, presence of comorbidities, and low vegetable intake. All
of the factors explained 35% of the total variation in HbA1c (adjusted R2 = 0.35;
p = 0.005).
The modifiable nutrition-related factors that were associated with glycemic
control (i.e., HL levels, physical activity, and vegetable intakes) were considered
the key nutrition component in the development of nutrition education materials
at Phase II. The SDNE curriculum emphasizes the use of the Plate Method and
"eating vegetables before carbohydrates." The developed SDNE had the HL
scale score of 57.1, indicating it was readable and acceptable among
participants. The SAM instruments score was 34 out of 40, indicating the SDNE
curriculum’s suitability. The dietitians and an endocrinologist confirmed the
content validity of the SDNE.
At Phase III, a total of 208 patients aged 20-64 years old with a confirmed
diagnosis of T2DM participated in the study. At 22 weeks, the interaction effects
were significant and more pronounced in NEG than CG for HbA1c (p < 0.001)
and other diabetes-related outcomes including on total cholesterol (p = 0.001),
low-density lipoprotein (p = 0.009), high-density lipoprotein (p < 0.001),
triglyceride (p = 0.01), waist circumference (p < 0.001), BMI (p = 0.008), total
energy (p < 0.001), carbohydrate (p < 0.001), and vegetable (p < 0.001) intakes.
Health belief model (HBM) constructs (p = 0.003), diabetes knowledge (DK) (p
= 0.004), and HL score (p < 0.001) were also improved. In conclusion, patients
with T2DM in Iraq had poor glycemic status, low HL, low vegetable intake, and
decreased levels of physical activity. These components were included in the
development of a simplified and visual educational material called SDNE. SDNE
was demonstrated to be effective in improving HbA1c, metabolic parameters,
dietary intake, and physical activity. Likewise, HBM, DK, and HL. SDNE can be
used in Clinics as simplified pictorial leaflets that will assist nutritionists in
providing appropriate and accessible nutritional education to patients with
T2DM. |
