Misclassification of sex in central cancer registries.

Background: Intrarecord edits on site-sex combinations are a standard tool to identify errors in the coding of sex in cancer registry data. However, the percentage of sex-specific cancers, like cervix, is low (20 percent of total invasive cases). Visual review and follow-back to improve the quality of the sex coding is labor intensive and typically only performed as a special project on subsets of data.

Behavioral risk factors for obesity during health transition in Vanuatu, South Pacific.

Unlabelled: The South Pacific archipelago of Vanuatu, like many developing countries, is currently experiencing a shift in disease burdens from infectious to chronic diseases with economic development. A rapid increase in obesity prevalence represents one component of this "health transition."

Objective: To identify behaviors associated with measures of obesity in Vanuatu.

A changing pattern of childhood BMI growth during the 20th century: 70 y of data from the Fels Longitudinal Study.

Background: The BMI distribution shifted upward in the United States between the 1960s and the 1990s, but little is known about secular trends in the pattern of BMI growth, particularly earlier in the century and early in childhood.

Objective: The objective was to examine differences in BMI growth in children born in 1929-1999.

Design: BMI curves from ages 2 to 18 y were produced for 855 European-American children in the Fels Longitudinal Study born in 1929-1953, 1954-1972, and 1973-1999.

Eighty-year trends in infant weight and length growth: the Fels Longitudinal Study.

Objectives: To investigate secular trends in weight and length growth from birth to 3 years of age in infants born from 1930 to 2008, and to assess whether these trends were associated with concurrent trends in pace of infant skeletal maturation and maternal body mass index.

Study Design: Longitudinal weight and length data from 620 infants (302 girls) were analyzed with mixed effects modeling to produce growth curves and predicted anthropometry for infants born from 1930 to 1949, 1950 to 1969, 1970 to 1989, and 1990 to 2008.

Results: The most pronounced differences in growth occurred in the first year of life.

Thyroid cancer incidence in highly observant Jewish neighborhoods in metropolitan New York City.

Background: Thyroid cancer incidence in New York State has increased rapidly in recent years, particularly in New York City and its surrounding metropolitan area. In 2007 among white non-Hispanics, incidence rates were about 40% higher in the New York City metropolitan area than in the rest of the state. Here we explore the extent to which living in neighborhoods with a high percentage of highly observant Jews may be associated with this pattern.

Patterns of childhood and adolescent overweight and obesity during health transition in Vanuatu.

Objective: Rapid economic development and subsequent changes in lifestyle and disease burdens ('health transition') is associated with increasing prevalence of obesity among both adults and children. However, because of continued infectious diseases and undernutrition during the early stages of transition, monitoring childhood obesity has not been prioritized in many countries and the scope of the problem is unknown. Therefore we sought to characterize patterns of childhood overweight and obesity in an early transitional area, the South Pacific archipelago of Vanuatu.

Behavioral changes associated with economic development in the South Pacific: health transition in Vanuatu.

Unlabelled: Health patterns are changing in developing countries; as diet and activity patterns change with economic development, chronic disease prevalence increases, which is a characteristic of health transition. The islands of Vanuatu (South Pacific) have varying rates of economic development and provide a natural experimental model of health transition.

Objectives: To characterize behavioral changes associated with modernization.

Relationships between body size and percent body fat among Melanesians in Vanuatu.

Obesity is a global epidemic, and measures to define it must be appropriate for diverse populations for accurate assessment of worldwide risk. Obesity refers to excess body fatness, but is more commonly defined by body mass index (BMI). Body composition varies among populations: Asians have higher percent body fat (%BF), and Pacific Islanders lower %BF at a given BMI compared to Europeans.

Blood pressure and lifestyle on Saba, Netherlands Antilles.

During the 20th century, infectious disease morbidity and mortality generally waned whereas chronic degenerative diseases posed a growing burden at the global level. The population on Saba, Netherlands Antilles has recently experienced such an epidemiologic transition, and hypertension was reported to be extraordinarily high, although no prevalences have been reported and relationships with lifestyle factors associated with rapid modernization have not been explored. In this study, a medical and demographic questionnaires, as well as body composition and blood pressure measures were collected from 278 Saban men and women aged 18-91 years.
