Factorial invariance of the Marianismo Beliefs Scale among Latinos in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

Objective: The Marianismo Beliefs Scale (MBS) assesses five components of marianismo, a cultural script of Latina gender role expectations. This study evaluated the MBS's psychometric properties across language, sex, and Latino subgroups (Mexican American, Central American, Cuban American, Dominican American, Puerto Rican, and South American).

Method: Study sample was derived from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study which consisted of a community sample of 4879 Latino adults aged 18-64 from four field centers (Miami, FL, USA; San Diego, CA, USA; Bronx, NY, USA; Chicago, IL, USA).

Sleeping oxygen saturation, rapid eye movement sleep, and the adaptation of postprandial metabolic function in insulin sensitive and resistant individuals without diabetes.

Aims: Sleeping oxygen saturation (SaO) and sleep stage duration have been linked with prediabetic alterations but the pathogenic pathways are not well understood. This study of insulin sensitive and resistant adults examined the effect on postprandial metabolic regulation of repeated mixed-meal challenges of different carbohydrate loading. The aim was to examine whether the relationship between lower sleeping oxygen saturation (SaO) and poorer fasting and postprandial metabolic function may be linked with reduced slow wave sleep (SWS) and rapid eye movement (REM) duration, independent of age, sex and total adiposity.
