Prevalence of Anemia and Iron Deficiency in Women of Reproductive Age in Cuba and Associated Factors.

This study aims to evaluate the prevalence of anemia and iron deficiency in women of reproductive age and the association with inflammation, global overweight, adiposity, and menorrhagia. A sample design of women of reproductive age from the Eastern, Central, and Havana Regions was carried out. Biochemical determinations of hemoglobin, serum ferritin, soluble transferrin receptors, leukocytes, C-reactive protein, alpha-1 acid glycoprotein, and homocysteine were performed.

Adjusting Iron Deficiency for Inflammation in Cuban Children Aged Under Five Years: New Approaches Using Quadratic and Quantile Regression.

Introduction: Ferritin is the best biomarker for assessing iron deficiency, but ferritin concentrations increase with inflammation. Several adjustment methods have been proposed to account for inflammation's effect on iron biomarker interpretation. The most recent and highly recommended method uses linear regression models, but more research is needed on other models that may better define iron status in children, particularly when distributions are heterogenous and in contexts where the effect of inflammation on ferritin is not linear.

Influence of Inflammation on Assessing Iron-Deficiency Anemia in Cuban Preschool Children.

Introduction: Anemia is a public health problem worldwide and is most prevalent in preschool children, for whom it is the most frequent cause of nutritional deficits. In turn, iron deficiency is the main cause of anemia, affecting 43% of children globally. Previous studies in Cuba show rates of iron deficiency in preschool children between 38.

Characterization of Deaths from Cirrhosis of the Liver in Cuba, 1987-2017.

INTRODUCTION Cirrhosis of the liver is a chronic disease that is widespread and irreversible. It represents the fi nal stage of numerous diseases that affect the liver. By the end of 2017, it was the 11th most common cause of death, with a loss of 41.

Patterns of Physical Activity and Associated Factors in Cubans Aged 15-69 Years.

INTRODUCTION Systematic measurement of population physical activity levels is an important component of public health surveillance. OBJECTIVES Describe patterns of physical activity in the Cuban population aged 15-69 years and identify factors associated with regular physical activity. METHODS A descriptive cross-sectional study was conducted using a complex sampling design, representative of urban and rural areas, sex and age groups, including 7915 individuals.

[Estimate methods used with complex sampling designs: their application in the Cuban 2001 health survey].

Objectives: To look at the individual features of three different methods used to estimate simple parameters--means, totals, and percentages, as well as their standard errors--and of logistic regression models, and to describe how such methods can be used for analyzing data obtained from complex samples.

Methods: Data from Cuba's Second National Survey of Risk Factors and Non-Communicable Chronic Ailments [Segunda Encuesta Nacional de Factores de Riesgo y Afecciones Crónicas No Transmisibles], which was conducted in 2001, were studied. A complex, stratified multi-stage cluster sampling design was used.
