How old do I look? Aging appearance and experiences of aging among U.S. adults ages 50-80.

Appearance is an indicator of age and life stage, which are linked to socially salient stereotypes and prejudices. Older adults' appearance-related perceptions and behaviors may affect their experiences of aging within broader society, which may in turn influence health. This study examined associations between two measures related to aging appearance-assessment of one's aging appearance relative to same-age peers and investing time or effort to look younger-positive and negative experiences of aging, and health using multivariable regression. Cross-sectional data were from a nationally representative sample of 2006 U.S. adults ages 50-80 (Mage = 63, 52% women, 71% White) who completed Wave 6 of the National Poll on Healthy Aging in 2019. The majority (59%) reported appearing relatively younger than peers, while fewer reported appearing the same age (35%) or older (6%). About a third (35%) reported investing in looking younger. Appearing relatively younger was associated with more positive (p < .001) and less negative experiences of aging (p = .019). Appearing relatively older showed the opposite relationships (p values < .001). Investing in looking younger was associated with more positive and more negative experiences of aging (p values < .001). Few sociodemographic variations were detected. More positive and less negative experiences of aging were associated with better physical and mental health (p values < .001). While aging appearance is often the basis for jokes, it may affect the quality of older adults' experiences of aging and associated health outcomes. Nuanced findings caution against framing youthful biases in aging appearance and investments in looking younger as solely negative (or positive).

Physical Obstruction of Nasal Cavities With Subsequent Asphyxia, Causes Lethality of Rats in an Acute Inhalation Study With Hydrophobic HMDZ Surface-Treated Synthetic Amorphous Silica (SAS).

The aim of the present study was to understand the mechanism of lethality associated with high dose inhalation of a low-density hydrophobic surface-treated SAS observed in some acute inhalation studies. It was demonstrated that physical obstruction of the upper respiratory tract (nasal cavities) caused the effects observed. Hydrophobic surface-treated SAS was inhaled (flow-past, nose-only) by six Wistar rats (three males and three females) in an acute toxicity study at a concentration of ~500 mg/m3 for an intended 4-hr exposure. Under the conditions of the test set-up, the concentration applied was found to be the highest that can be delivered to the test animal port without significant alteration of the aerosol size distribution over time. None of the test- material-exposed animals survived the planned observation time of 4 h; three animals died between 2 34 h after starting exposure and cessation of exposure at 3 14 h, two died after transfer to their cages and the remaining animal was sacrificed due to its poor condition and welfare considerations. Histology accomplished by energy dispersive X-ray (EDX) analysis demonstrated that test material particles agglomerated and formed a gel-like substrate that ultimately blocked the upper respiratory airways, which proved fatal for the rat as an obligatory nose breather. This observation is in line with the findings reported by Hofmann et al. showing a correlation between lethality and hydrophobicity determined by contact angle measurement. The aerosol characterizations associated with this study are provided in detail by Wessely et al.

Experiences of Everyday Ageism and the Health of Older US Adults.

Importance: Major incidents of ageism have been shown to be associated with poorer health and well-being among older adults. Less is known about routine types of age-based discrimination, prejudice, and stereotyping that older adults encounter in their day-to-day lives, known as everyday ageism. Objective: To examine the prevalence of everyday ageism, group differences and disparities, and associations of everyday ageism with indicators of poor physical and mental health. Design, Setting, and Participants: This cross-sectional study was conducted using survey data from the December 2019 National Poll on Healthy Aging among a nationally representative household sample of US adults ages 50 to 80 years. Data were analyzed from November 2021 through April 2022. Exposures: Experiences of everyday ageism were measured using the newly developed multidimensional Everyday Ageism Scale. Main Outcomes and Measures: Fair or poor physical health, number of chronic health conditions, fair or poor mental health, and depressive symptoms. Results: Among 2035 adults ages 50 to 80 years (1047 [54.2%] women; 192 Black [10.9%], 178 Hispanic [11.4%], and 1546 White [71.1%]; mean [SD] age, 62.6 [8.0] years [weighted statistics]), most participants (1915 adults [93.4%]) reported regularly experiencing 1 or more forms of everyday ageism. Internalized ageism was reported by 1664 adults (81.2%), ageist messages by 1394 adults (65.2%), and interpersonal ageism by 941 adults (44.9%). Mean Everyday Ageism Scale scores were higher for several sociodemographic groups, including adults ages 65 to 80 years vs those ages 50 to 64 years (11.23 [95% CI, 10.80-11.66] vs 9.55 [95% CI, 9.26-9.84]) and White (10.43 [95% CI, 10.20-10.67]; P < .001) and Hispanic (10.09 [95% CI, 9.31-10.86]; P = .04) adults vs Black adults (9.23 [95% CI, 8.42-10.03]). Higher levels of everyday ageism were associated with increased risk of all 4 negative physical and mental health outcomes examined in regression analyses (with odds ratios [ORs] per additional scale point as high as 1.20 [95% CI, 1.17-1.23] for depressive symptoms and b = 0.039 [95% CI, 0.029-0.048] for chronic health conditions; P values < .001). Internalized ageism was the category associated with the greatest increase in risk of poor outcomes for all health measures (with ORs per additional scale point as high as 1.62 [95% CI, 1.49-1.76] for depressive symptoms and b = 0.063 [95% CI, 0.034-0.092] for chronic health conditions; P values < .001). Conclusions and Relevance: This study found everyday ageism to be prevalent among US adults ages 50 to 80 years. These findings suggest that commonplace ageist messages, interactions, and beliefs may be harmful to health and that multilevel and multisector efforts may be required to reduce everyday ageism and promote positive beliefs, practices, and policies related to aging and older adults.
