Knowledge and behaviors regarding salt intake in Mozambique

Area of Science:

• Public Health Nutrition
• Dietary Habits Research
• Health Education Strategies

Background:

• Population salt intake is influenced by health education and regulatory policies.
• Understanding current salt consumption knowledge and behaviors is crucial for effective interventions.

Purpose of the Study:

• To assess knowledge and behaviors related to dietary salt intake in Mozambique.
• To identify areas for improvement in public health strategies for salt reduction.

Main Methods:

• Cross-sectional study of 3116 individuals aged 15-64 in Mozambique (2014/2015).
• Utilized the Stepwise Approach to Chronic Disease Risk Factor Surveillance with a 12-question dietary salt module.
• Analyzed data on self-reported intake, knowledge of health effects, and salt control behaviors.

Main Results:

• 7.4% perceived excessive salt intake; 25.9% frequently added salt/seasoning.
• 8% found reducing dietary salt unimportant; 16.9% were unaware of health risks.
• High prevalence of lacking salt-reducing behaviors (e.g., 74.9% not limiting processed foods, 95% not buying low-salt alternatives).
• Hypertension awareness correlated with better knowledge and fewer high-intake behaviors.

Conclusions:

• While awareness of salt's health risks is present, self-reported intake and control behaviors indicate significant room for improvement.
• Findings support the development of population-level salt reduction policies in Mozambique.
