First Nations and Inuit mental health and the Non-Insured Health Benefits program: Urgent priorities for evaluation.

The mental health needs and disparities facing First Nations and Inuit in Canada far exceed those of the general population and yet accessing culturally safe care remains a serious challenge. One means for accessing mental health care is through the Non-Insured Health Benefits (NIHB) mental health counselling program run by Indigenous Services Canada. However, evaluations of the efficacy of the NIHB's mental health counselling program remain entirely absent in the academic literature and this is startling given that this program receives significant federal funding to care for a population that experiences extreme marginalization. The following commentary will present three challenges observed with the present state of the program in the areas of service accessibility, the need for an Indigenous mental health workforce, and culturally safe care. For each challenge presented, we make recommendations on how to improve the program in its current state. The conclusion of this article advocates for a broader evaluation of the NIHB mental health counselling program from the perspective of its service users and its registered mental health professionals. This type of evaluation is commensurate with the Calls to Action outlined by the Truth and Reconciliation Commission of Canada.

RéSUMé: Les besoins en santé mentale et les disparités rencontrés par les Premières Nations et les Inuits au Canada dépassent de loin ceux de la population générale, et pourtant, l'accès à des soins culturellement sécuritaires demeure un sérieux défi. Une des manières d'accéder aux soins de santé mentale est par le biais du programme de counselling en santé mentale des Services de santé non assurés (SSNA), géré par Services aux Autochtones Canada. Cependant, les évaluations de l'efficacité du programme de counselling en santé mentale des SSNA sont entièrement absentes de la littérature académique, ce qui est surprenant compte tenu que ce programme reçoit un financement fédéral important pour prendre en charge une population qui vit une marginalisation extrême. Le commentaire suivant présentera trois défis observés avec l'état actuel du programme dans les domaines de l'accessibilité des services, la nécessité d'une main-d'œuvre en santé mentale autochtone, et des soins culturellement sécuritaires. Pour chaque défi présenté, nous faisons des recommandations sur la manière d'améliorer le programme dans son état actuel. La conclusion de cet article plaide pour une évaluation plus large du programme de counselling en santé mentale des SSNA du point de vue de ses utilisateurs de services et des professionnels de la santé mentale inscrits. Ce type d'évaluation est conforme aux Appels à l'action décrits par la Commission de vérité et réconciliation du Canada.

The association between Mediterranean diet adherence and allostatic load in older adults.

Allostatic load (AL) is a multisystemic index of biological wear and tear which is associated with poor health outcomes. In recent years, researchers have examined the association between dietary pattern intake and AL; however, no studies to date have examined the relationship between AL and consumption of a Mediterranean diet. Blood and urine samples were collected from 201 community-dwelling older adults who completed a Food Frequency Questionnaire (FFQ). A Mediterranean Diet Score (MDS) was calculated based on previous recommendations and a sex-based AL index was calculated using a count-based approach for 16 biomarkers associated with neuroendocrine, immune, cardiovascular, or metabolic function. It was hypothesized that a higher MDS would be associated with lower AL, and that this association would be particularly robust for the immune and metabolic subcomponents of the AL index. In support of the primary study hypotheses, generalized linear models revealed a significant inverse relationship between MDS and AL (ß = -0.03, P = 0.037). However, subcomponents of the AL model were not significantly associated with MDS. Exploratory sub-group analyses by sex suggested that the association between AL and MDS was more robust in male than in female participants. The current findings are interpreted with caution given the study design and sample characteristics. Nonetheless, these findings contribute to the literature supporting the Mediterranean diet as an important lifestyle behavior that may minimize AL, and therefore support healthy aging.

Chronic noise exposure has context-dependent effects on stress physiology in nestling Tree Swallows (Tachycineta bicolor).

Anthropogenic noise is increasing in intensity and scope, resulting in changes to acoustic landscapes and largely negative effects on a range of species. In birds, noise can mask acoustic signals used in a variety of communication systems, including parent-offspring communication. As a result, nestling birds raised in noise may have challenges soliciting food from parents and avoiding detection by predators. Given that passerine nestlings are confined to a nest and therefore cannot escape these challenges, noise may also act as a chronic stressor during their development. Here, we raised Tree Swallow (Tachycineta bicolor) nestlings with or without continuous, white noise to test whether noise exposure affected baseline and stress-induced plasma, integrated feather corticosterone levels, and immune function. Stress physiology and immune function may also vary with the competitive environment during development, so we also examined whether noise effects varied with brood size and nestling mass. We found that overall, exposure to noise did not alter nestling stress physiology or immune function. However, light nestlings raised in noise exhibited lower baseline plasma and integrated feather corticosterone than heavy nestlings, suggesting alternative physiological responses to anthropogenic stimuli. Furthermore, light nestlings in larger broods had reduced PHA-induced immune responses compared to heavy nestlings, and PHA-induced immune responses were associated with higher levels of baseline plasma and feather CORT. Overall, our findings suggest that noise can alter the stress physiology of developing birds; however, these effects may depend on developmental conditions and the presence of other environmental stressors, such as competition for resources. Our findings may help to explain why populations are not uniformly affected by noise.
