4.22. Biochemical measurements

Diabetes as a risk factor for NCDs was assessed by means of fasting blood glucose and HbA1c measurements.

Fig. 40 shows the mean fasting blood glucose of the study population, including those currently on medication for diabetes (but excluding non-fasting recipients), was 97.8 mg/dl. The increases in levels for both sexes, from 86.3 mg/dl in the group aged 15–29 to 116.2 mg/dl in the group aged ≥ 70, underlines that this value increases in general with age.

Of all the respondents, 7.9% had impaired fasting glycaemia (plasma venous value of 110–126 mg/dl); 8.1% for men and 7.7% for women. The frequency increased from 4.7% in the group aged 15–29 to 12.6% in the group aged ≥ 70 (Fig. 41).

Low HDL is defined as a plasma venous value <  50mg/dl for women and <  40mg/dl for men; 52.3% of respondents had low HDL (55.6% for men and 49.1% for women) (Fig. 46). In addition, 61.7% of the men aged 30–44 was below the optimal level of HDL cholesterol; this proportion fell to 40.4% in those aged ≥70; this percentage decreased with age in general. The percentage of HDL cholesterol below the optimal level for women was similar in all age groups.

Table 55 shows that the mean fasting triglycerides level for all respondents (excluding non-fasting respondents) was 122.8 mg/dl; 129.0 mg/dl for men and 116.7 mg/dl for women. The mean level increased from 99.1 mg/dl in the group aged 15–29 to 144.5 mg/dl in the group aged 45–59, and tended to decrease in older age.

Respondents’ mean salt intake was 9.9 g per day; 11.0 g for men and 8.7 g for women.

4.22.1. Conclusions

Some of the most important results from biochemical measurements of respondents included the following:

● the mean fasting glucose level was 97.8 mg/dl (96.2 mg/dl for men and 99.3 mg/dl for women) and levels increased in older age, including those currently on medication for diabetes;

● 7.9% had impaired fasting blood glycaemia levels (≥ 110 mg/dl and < 126 mg/dl and this proportion was higher among men (8.1%) than women (7.7%);

● 11.1% had raised fasting blood glucose or currently on medication for diabetes, without significant differences between men and women;

● mean HbA1c levels were also similar in men and women, although the frequency of raised HbA1c (≥ 6.5%) was 12.0% and increased with age;

● 13.3% had raised HbA1C (≥6,5%) or were currently on medication for diabetes (12.7% for men and 13.8%

for women)

● 17.3% had fasting plasma venous glucose ≥ 126 mg/dl or HbA1c ≥ 6.5% or were currently on medication for raised blood glucose; the frequency of all three increased with age;

● the mean total blood cholesterol level was 161.2 mg/dl, although women (167.3 mg/dl) tended to have higher levels than men (154.9 mg/dl);

● 24.7% had a raised total cholesterol level, with a higher proportion in women (28.5%) than men (20.9%);

● suboptimal levels of HDL cholesterol were found in 55.6% of men (< 40 mg/dl) and 49.1% of women (< 50 mg/dl);

● men had higher mean levels of fasting triglycerides, and 19.9% of men and 13.6% of women had raised triglycerides (≥ 180 mg/dl);

● the mean daily intake of salt was 9.9 g and men consumed more than women on average (11.0 g per day versus 8.7 g per day).
