“…Using the WHO cut-offs for national prevalence of vitamin A deficiency, Iran should by this standard be considered a country with severe vitamin A insufficiency prevalence (<0.7 µmol/L) in 2001. In contrast, reports from the north of Iran, Marand district, in 2002 showed that 2.1% of child-bearing women had a deficiency level of vitamin A (<0.7 µmol/L) but 18% had values between insufficient or suboptimal level of vitamin A (19). Prevalence of deficiency levels (<0.36 µmol/L) was 6.6% nation-wide and similar to the average global prevalence of maternal vitamin A deficiency in developing countries (7%) (20).…”

“…A low access in the south of Iran to main sources of vitamin A (dairy products, vegetables, and fruits) may be related to the hot and dry climate in this region (27). One study in northwest of Iran showed that the important sources of vitamin A in child-bearing women were nuts and green leaves, products that were not typical of other populations (19). Vegetables and fruits provide carotenoids equivalent to more than 50% of vitamin A (4).…”

BackgroundVitamin A deficiency is considered as one of the public health problems among pregnant women worldwide. Population representative data on vitamin A status in pregnancy have not previously been published from Iran.ObjectivesThe aim of this study was to publish data on vitamin A status in pregnant women in all the provinces of Iran in 2001, including urban and rural areas, and to describe the association of vitamin A status with maternal age, gestational age, and parity.DesignThis descriptive cross-sectional study was conducted on 3,270 healthy pregnant women from the entire country, 2,631 with gestational age ≤36 weeks, and 639 with gestational age >36 weeks. Vitamin A status was determined in serum using high-performance liquid chromatography.ResultRetinol levels corresponding to deficiency were detected in 6.6% (<0.36 µmol/L) and 18% had insufficient vitamin A levels (≥0.36–<0.7 µmol/L). Suboptimal level of serum retinol was observed in 55.3% of the pregnant women (0.7–1.4 µmol/L). Only about 20% of the women had optimal values (>1.4 µmol/L). The level of serum retinol was lower in older pregnant women (p=0.008), and at higher gestational age (p=0.009). High vitamin A levels were observed in pregnant women in the central areas of Iran and the lowest values in those in the southern areas of Iran.ConclusionsThe vitamin A status was good in 2001 but should be closely monitored also in the future. About 25% of pregnant women had a vitamin A status diagnosed as insufficient or deficient (<0.7 µmol/L). The mean serum retinol decreased as the gestational age increased. The clinical significance of this finding should be further investigated, followed by a careful risk group approach to supplementation during pregnancy.

“…A wide variety of fruits and vegetables are grown and consumed and meat, poultry and fish are highly valued, but relatively expensive. Nuts and fresh leafy greens, including plants used in other cuisines as herbs in small quantities, are consumed regularly and in quantities that make important contributions to nutrient intake 11 . Tea is the major beverage.…”

Objective: To describe the emergence of the nutrition transition, and associated morbidity shifts, in the Islamic Republic of Iran. Design: Review and analysis of secondary data relating to the socio-political and nutritional context, demographic trends, food utilisation and consumption patterns, obesity, and diet-related morbidity. Results and conclusions: The nutrition transition in Iran is occurring rapidly, secondary to the rapid change in fertility and mortality patterns and to urbanisation. The transition is occurring against the backdrop of lack of sustained economic growth. There is considerable imbalance in food consumption with low nutrient density characterising diets at all income levels, over-consumption evident among more than a third of households, and food insecurity among 20% of the population. Obesity is an emerging problem, particularly in urban areas and for women, and both diabetes and other risk factors for heart disease are becoming significant problems.

The aim of this study was to compare the dietary intake and serum levels of some selected carotenoids of lung cancer patients with healthy subjects. Thirty-five lung cancer patients and 33 healthy people were enrolled into this case-control study. Daily intake of nutrients was estimated using a semiquantitative food frequency questionnaire and a 3-day 24-h food recall questionnaire. The concentration of serum beta-carotene and lycopene were analyzed using a high performance liquid chromatography method. Case and control groups did not differ by the means of age, gender, smoking habits, weight, body mass index, mean daily energy intake, mean daily fat intake, and the percentage of daily energy provided by fat to total daily energy intake. The beta-carotene and lycopene intake of the case subjects was 96% and 195% greater than that of the control subjects. Daily intake of fruits and vegetables in the cancer group was higher than the control group. However, the serum concentration of 118% beta-carotene and 60% lycopene were higher in the control group. Despite a higher daily dietary intake of beta-carotene and lycopene by lung cancer patients, serum beta-carotene and lycopene concentrations were significantly lower than the group without cancer.
