Modeling US adult obesity trends: a system dynamics model for estimating energy imbalance gap.

Objectives: We present a system dynamics model that quantifies the energy imbalance gap responsible for the US adult obesity epidemic among gender and racial subpopulations.

Methods: We divided the adult population into gender-race/ethnicity subpopulations and body mass index (BMI) classes. We defined transition rates between classes as a function of metabolic dynamics of individuals within each class.

The inconsistent mediating effects of psychosocial work characteristics on the education-health relationship.

This study examined the relationship between psychosocial work characteristics and educational disparities in health. Informed by the evidence on the relationship between work pressure and higher education, we suggested reframing the distribution of psychosocial work characteristics in the context of education. We differentiated psychosocial work resources from demands and hypothesized that the inconsistent mediation effects of psychosocial resources and demands are associated with educational status.

The racial crossover in family complexity in the United States.

This article examines the evolution of the black extended family by documenting a black-white crossover in the proportions of unmarried adults living in complex households after the middle of the twentieth century. We demonstrate significant racial differences in the trends in complex house-hold residence over the life course, characterized by far greater declines in complex living among whites, particularly at younger ages. In this context, the higher level of family extension that recent research has found typifies black families is both a relatively new phenomenon and one that is not just limited to single-parent families; it characterizes all ages, those with and without children, and men as well as women.

Childhood residential stability and health at midlife.

Results: Neighborhood stability in childhood is associated with a significant increase in the likelihood that an individual will rate his or her global health highly in midlife.

Regional clustering of shared neutralization determinants on primary isolates of clade C human immunodeficiency virus type 1 from South Africa.

Clade C is one of the most prevalent genetic subtypes of human immunodeficiency virus type 1 (HIV-1) in the world today and one of the least studied with respect to neutralizing antibodies. Most information on HIV-1 serology as it relates to neutralization is derived from clade B. Clade C primary isolates of HIV-1 from South Africa and Malawi were shown here to resemble clade B isolates in their resistance to inhibition by soluble CD4 and their sensitivity to neutralization by human monoclonal antibody immunoglobulin G1b12 and, to a lesser extent, 2F5.

Immunization with recombinant canarypox vectors expressing membrane-anchored glycoprotein 120 followed by glycoprotein 160 boosting fails to generate antibodies that neutralize R5 primary isolates of human immunodeficiency virus type 1.

Antibodies generated by candidate HIV-1 vaccines in a phase I clinical trial were assessed for neutralizing activity with a panel of eight well-characterized, genetically diverse clade B primary isolates having an R5 phenotype. The vaccines consisted of one of three different recombinant canarypox vectors expressing membrane-anchored HIV-1(MN)gp120 (ALVAC vCP205, vCP1433, and vCP1452) followed by boosting with a soluble gp160 hybrid consisting of MNgp120 and the majority of gp41 from strain IIIB. Serum samples from a subset of volunteers in each arm of the trial, containing moderate to high titers of neutralizing antibodies to HIV-1 MN, were analyzed.
