In a logistic model with relevant predictors, zinc deficiency was positively associated with gender and with serum albumin level. Results. Their estimate indicates at least five African countries have a total population with zinc deficiency in excess of 40% – Malawi (47%), Zambia (45%), Ethiopia (44%), Tanzania (42%) and Nigeria (41%). Zinc deficiency is a major cause of childhood morbidity and mortality in developing countries (3, 4).Deficiency itself is common, although its prevalence varies in different countries, as judged from differences in plasma zinc between populations ().Zinc supplements reduce the incidence of diarrhea and probably mortality ().Thus, the 2008 Copenhagen consensus meeting … According to the studies and surveys done by several world health organizations, about 31% of the entire population is at risk of zinc deficiency. Zinc deficiency affects around 17% of the world’s population, mostly in developing countries. Zinc intake is closely related to protein intake; as a result, zinc deficiency is an important component of nutritionally related morbidity worldwide . There was a significant difference in zinc deficiency prevalence between the control group (14.4%) and the patient group (41.0%) (χ 2 = 44.81, df = 1, p<0.001). SOLUTION: Zinc fertilizer increases crop yield and improves water uptake, resulting in healthier, stronger crops. Zinc deficiency is the most common micronutrient deficiency, affecting more than 50% of the world’s agricultural soils. Zinc is one of the minerals that people all over the world tend to lack. The role of zinc deficiency as an important cause of morbidity and impaired linear growth has prompted the need to identify indicators of population zinc status. In other words, when a higher than expected percentage of individuals in a population have low serum zinc con - centrations, it can be inferred that there is an elevated risk of zinc deficiency occurring within the population [1, 3, 6, 7]. Most of the affected are poor, and rarely consume foods rich in highly bioavailable zinc, while subsisting on foods that are rich in inhibitors of zinc absorption and/or contain relatively small amounts of bioavailable zinc. Although it has been known for more than six decades that zinc is essential for the growth of micro-organisms, plants, and animals, until 1961 it was believed that zinc deficiency in humans could never occur. Zinc deficiency was, for example, reported to affect the immune response and the endocrine system and to induce and modify brain disorders. National risk of zinc deficiency based on the prevalence of childhood stunting and the estimated prevalence of inadequate zinc intake (Wessells & Brown, 2012) In fact, zinc deficiency is one of the leading risk factors for disease in developing countries. Severe zinc deficiency can even manifest as skin-related symptoms. Zinc deficiency is prevalent in many areas of the world and is a diagnostically challenging condition. Individuals with IBS had significantly higher ratios of copper to zinc (1.70 vs 1.55, P =.048) and were more likely to have ratios >1.8 (OR, 1.79; 95% CI, 1.02-3.13), which suggests an underlying zinc deficiency. 5. Because the largest source of dietary zinc in the study population was milk, this deficiency may be the result of these individuals’ avoidance of dairy. Zinc is essential to good health and immunocompetence. Community-based data relating to factors influencing zinc deficiency among preschool children in India are inadequate. Besides hereditary zinc deficiency, zinc deficiency – at least in mild forms – is nowadays a very abundant health issue. The risk of zinc deficiency is considered to be elevated and a likely public health problem when the prevalence of inadequate absorbable zinc intakes is >25% and if stunting rates are >20%. Background Adequate zinc nutrition is essential for adequate growth, immunocompetence and neurobehavioral development, but limited information on population zinc status hinders the expansion of interventions to control zinc deficiency. The present analyses were conducted to: (1) estimate the country-specific prevalence of inadequate zinc intake; and (2) investigate relationships … Data of a large, double-blinded, randomized, controlled zinc-supplementation trial were used for assessing the descriptive epidemiology of zinc deficiency … Zinc deficiency impairs immune function and increases the susceptibility to infection, restricts physical growth and affects pregnancy outcome. However, zinc deficiency symptoms have become such a widespread problem globally that the World Health Organization (WHO) reports that 31 percent of the world’s population is zinc deficient. It protects skin health. ( 1 ) In America, we live in a bubble of fortified foods and multivitamin supplements that are available at nearly every grocery store. Total parenteral nutrition regimens usually include trace amounts of zinc. Studies have found some benefit of zinc supplementation in this population, including to head growth in infants between 23 and 28 weeks. This occurs because zinc deficiency can change the way the kidneys process sodium. Most high-income countries, especially across Europe, North America, Oceania and Central Asia have incidences of zinc deficiency below 5-10 percent of the total population. The global prevalence of zinc deficiency, measured as the share of the total population with intakes below physiological requirements, 1990-2005. Acquired zinc deficiency can occur as a result of impaired absorption of this metal. Thus, post hoc power calculation was not performed using the effect size observed in the analysis, as recommended (Levine & Ensom, 2001 ). Cutaneous manifestations typically occur in moderate to severe zinc deficiency and present as alopecia and dermatitis in the perioral, acral, and perineal regions. Zinc supplementation trials assessing the response of growth and immunity have assisted in identifying populations at risk of zinc deficiency and the factors that contribute. Conservative estimates suggest that 25% of the world’s population is at risk of zinc deficiency ( 12 ). The baseline sample size was fixed and no prior studies have shown “true” effect sizes for zinc deficiency and anaemia in a similar population. These include: Proven zinc deficiency and zinc-losing conditions. Zinc deficiency in infants and young children is correlated with growth and development issues. Besides hereditary zinc deficiency, zinc deficiency – at least in mild forms – is nowadays a … Its deficiency is generally associated with a negative impact on overall health, increased susceptibility to disease, and infections [9-12]. A recent trial in Ethiopia demonstrated a high risk of zinc deficiency among young children, particularly among those … Zinc acetate is used to treat Wilson's disease . Zinc is a trace element essential to the gastrointestinal, immune, integumentary, reproductive, and central nervous systems. About one-third of the global population is considered to have a zinc deficiency, making this a common problem. Data on zinc deficiency based on population surveys are still lacking from many developing countries (13, 14). IZiNCG is the International Zinc Nutrition Consultative Group whose primary objectives are to promote and assist efforts to reduce global zinc deficiency, with particular emphasis on the most vulnerable populations of low-income countries. The prevalence of zinc deficiency across Sub-Saharan Africa and South Asia is higher, and variable between 15 to 50 percent. Zinc supplements must be used with caution in view of the dangers of zinc excess and zinc toxicity. It is now clear that nutritional deficiency of zinc is widely prevalent and its morbidities are severe. For the study, researchers from Emory University examined… Bahmer and Bader have observed that zinc and biotin levels are reduced in patients with chronic alcohol use disorder and this may be associated with skin-related symptoms such as severe skin inflammation, the formation of rashes, crusts and scales, alopecia.. A case report published in 2000 … Indications for zinc supplementation. ... By 2050 the world’s population will reach 9.1 billion. Less precise estimates, such as those based on national food balance sheets and on the prevalence of clinical manifestations of zinc deficiency, like stunting and diarrhea in children, have been used instead ( 15 ). A new study finds that having low levels of zinc may increase a person’s risk of high blood pressure or hypertension. Zinc is an essential trace element for humans and plays a critical role both as a structural component of proteins and as a cofactor in about 300 enzymes. Common signs and symptoms of a zinc deficiency include canker sores, deformed nails, hair loss, and rashes. Zinc deficiency (ZnD) is also prevalent in 25.6% of the population based on serum Zn level tests. In Pakistan, the most recent national nutrition survey indicated that over 40% of women are zinc deficient. Zinc deficiency appears to be a public health problem in almost all LMICs, irrespective of the indicators used for assessment (prevalence of low height‐ or length‐for‐age >20% among children under 5 years of age; prevalence of low plasma zinc among the population >20%; prevalence of insufficient zinc … Serum zinc was used to determine the zinc status of the population because it is known as the best biomarker for zinc. Zinc Deficiency: Descriptive Epidemiology and Morbidity among Preschool Children in Peri-urban Population in Delhi, India October 2009 Journal of Health Population and Nutrition 27(5):632-9 The majority of countries found that zinc deficiency is a public health concern, and it is recommended that preventive zinc interventions should be considered in these settings.
