Serum selenium concentration in Mashhad prisoners, Iran

Area of Science:

• Nutritional biochemistry
• Public health
• Environmental health

Background:

• Selenium is an essential trace element crucial for various physiological functions.
• Nutritional status assessments are vital for incarcerated populations due to potential health disparities.
• Geographic location and dietary patterns can influence selenium levels.

Purpose of the Study:

• To assess serum selenium concentrations in prisoners at Mashhad Central Prison, Iran.
• To determine the prevalence of selenium deficiency within this specific demographic.
• To explore potential differences in selenium status based on gender and age.

Main Methods:

• A cross-sectional study was conducted with 435 prisoners (387 men, 48 women) from May to June 2008.
• Multistage sampling ensured representation across gender, age groups, and crime types.
• Serum selenium levels were quantified using atomic absorption spectrophotometry.

Main Results:

• The mean serum selenium concentration was 121±20 ug/l.
• A notable 9.7% of the prisoner sample exhibited selenium deficiency.
• Selenium deficiency was significantly more prevalent in women (25.5%) than in men (7.8%), with a p-value of 0.00.

Conclusions:

• The selenium status of prisoners in Mashhad Central Prison warrants attention.
• Women prisoners represent a higher-risk group for selenium deficiency.
• Findings underscore the need for targeted health interventions and policy considerations for this vulnerable population.
