Abstract
Internalized homophobia, or the internalization of negative attitudes toward one's sexual minority identity, is associated with sexual risk behaviors among young sexual minority men (YSMM). However, the formation and maintenance of secure or insecure socio-emotional bonds with friends, family members, and intimate partners (i.e., adult attachment) may mitigate or exacerbate the negative effects of exposure to internalized homophobia. Nevertheless, little is known about how adult attachment influences the association between internalized homophobia and sexual risk behaviors (e.g., condomless anal sex) among YSMM. Thus, this study examined the potential moderating effect of adult attachment on the association between internalized homophobia and condomless anal sex (CAS) behaviors (i.e., insertive CAS and receptive CAS) among a sample of N = 268 YSMM who participated in the study between June 2015-March 2017 using zero-inflated Poisson regression models. We found that adult attachment anxiety, but not adult attachment avoidance, significantly moderated the association between internalized homophobia and receptive CAS behaviors such that those higher on adult attachment anxiety and internalized homophobia had fewer receptive CAS events over the preceding 30 days as compared to those lower on adult attachment anxiety and internalized homophobia. Research efforts should focus on unpacking the complex associations between adult attachment, internalized homophobia, and sexual risk behaviors among YSMM.

Discrimination, Smoking, and Cardiovascular Disease Risk: A Moderated Mediation Analysis With MESA. J Am Heart Assoc 2024; 13:e032659. [PMID: 38390806 PMCID: PMC10944061 DOI: 10.1161/jaha.123.032659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 01/31/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND Carotid intima-media thickness (cIMT) and carotid plaque are reliable indicators of cardiovascular disease risk, and research highlights that racial and ethnic minority individuals generally exhibit higher cIMT and carotid plaque than White individuals. At present, the mechanisms driving these disparities among different racial and ethnic and biological sex groups are poorly understood. METHODS AND RESULTS Data came from the baseline examination of MESA (Multi-Ethnic Study of Atherosclerosis). A total of 6814 participants aged 45 to 84 years free of clinical cardiovascular disease completed assessments on health behavior and perceived discrimination. Four sex-stratified moderated mediation models examined associations between discrimination, cigarette smoking, and mean cIMT and plaque. We hypothesized that cigarette use would mediate the association between discrimination and carotid artery disease features, and that these would differ by race and ethnicity. Indirect effects of discrimination on plaque were observed among Hispanic women such that discrimination was associated with cigarette use and, in turn, higher plaque (β=0.04 [95% CI, 0.01-0.08]). Indirect effects of discrimination on mean cIMT were found among Hispanic (β=0.003 [95% CI, 0.0001-0.007]) and White men (β=0.04 [95% CI, 0.01-0.08]) such that discrimination was associated with cigarette use and, in turn, higher cIMT. Finally, a positive indirect effect of discrimination on plaque was observed among Hispanic men (β=0.03 [95% CI, 0.004-0.07]). No other racial and ethnic differences were observed. CONCLUSIONS To understand and address social determinants of cardiovascular disease, researchers must incorporate an intersectional framework that will allow us to understand the complex nature of discrimination and cardiovascular disease risk for individuals of varying intersecting identities and social positions.

Assessment of a Daily Diary Study Including Biospecimen Collections in a Sample of Sexual and Gender Minority Young Adults: Feasibility and Acceptability Study. JMIR Form Res 2024; 8:e52195. [PMID: 38373036 PMCID: PMC10912985 DOI: 10.2196/52195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 12/21/2023] [Accepted: 01/09/2024] [Indexed: 02/20/2024] Open
Abstract
BACKGROUND Young sexual minority men (YSMM) engage in cardiometabolic risk behaviors (eg, substance use) at higher rates than their heterosexual counterparts. Theory and previous research suggest that these risk behaviors may stem, in part, from exposure to minority stress (ie, discrimination based on sexual identity and other identities such as race). OBJECTIVE This pilot study examined the feasibility and acceptability of a virtual 2-day daily diary study that examined daily experiences with discrimination, cardiometabolic risk behaviors (ie, sleep, physical activity, and substance use behaviors), and patterns of physiological stress and inflammation among YSMM aged 18 to 35 years. METHODS Participants (n=20) were recruited from the greater New York metropolitan area and engaged in a 2-day daily diary protocol wherein they provided web-based consent, took a web-based baseline survey, and then, starting the next day, provided 3 saliva samples a day for 2 consecutive days to measure salivary cortisol, engaged in 3 daily diaries per day, and provided 1 blood spot sample via the finger prick method to measure high-sensitivity C-reactive protein. At follow-up, participants were interviewed via videoconferencing to ascertain their experiences and feelings related to the study protocol. Qualitative analyses explored the feasibility and acceptability of the study protocol, and exploratory quantitative analyses explored the descriptive statistics and Pearson correlations among the main study variables of interest. RESULTS The retention rate was high (19/20, 95%) in our study sample. Qualitative analyses demonstrated that participants were willing to engage in similar, longer-term studies (eg, studies that include both week and weekend days) in the future and suggested the feasibility and acceptability of our study protocol among YSMM. However, participants noted several areas for improvement (eg, redundancy of survey items and difficulty pricking one's finger) that should be considered in future research. Preliminary quantitative analyses revealed a moderate negative correlation between everyday discrimination and mean cortisol levels (r=-0.51; P=.03). Furthermore, descriptive analyses suggest that that daily cortisol curves differ across races or ethnicities among YSMM. White and other-identified YSMM experienced the highest cortisol awakening response (mean 0.39, SD 0.21 µg/dL for White participants; mean 0.34, SD 0.34 µg/dL for others) with the steepest decline around bedtime (mean 0.05, SD 0.04 µg/dL for White participants; mean 0.09, SD 0.13 µg/dL for others) followed by a lower cortisol awakening response (mean 0.31, SD 0.11 µg/dL for Hispanic participants; mean 0.23, SD 0.15 µg/dL for Black participants) and a slower decline around bedtime (mean 0.10, SD 0.09 µg/dL for Hispanic participants; mean 0.03, SD 0.02 µg/dL for Black participants) among Hispanic and Black YSMM. CONCLUSIONS Overall, the results suggest that similar study protocols are feasible and acceptable among YSMM. Future research should highlight the pathways through which cardiovascular disease risk may arise among YSMM using longer-term study designs and more diverse study samples.

A national examination of discrimination, resilience, and depressive symptoms during the COVID-19 pandemic: the All of Us Research Program. Front Psychol 2023; 14:1175452. [PMID: 37823074 PMCID: PMC10562571 DOI: 10.3389/fpsyg.2023.1175452] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 09/11/2023] [Indexed: 10/13/2023] Open
Abstract
Objective To examine the impact of resilience on the association between discrimination and trajectories of depressive symptoms during the COVID-19 pandemic across racial and ethnic groups. Methods Data were drawn from 5 waves of the All of Us Research Program's survey on the impact of COVID-19 on the lives of American adults. Linear mixed-effects models were fitted to assess the association between discrimination exposure throughout the pandemic and depressive symptoms over time. An interaction term was introduced between resilience and discrimination exposure to assess if resilience buffered the association between discrimination and depressive symptoms over time. Race-stratified linear mixed-effects models examined racial/ethnic differences in the association between resilience, discrimination, and depressive symptoms over time. Results Fifty-one thousand nine hundred fifty-eight participants completed surveys between May and December of 2020. Results indicated that exposure to more discrimination was associated with increasing trajectories of depressive symptoms over time (b = 0.48, p < 0.001). However, resilience moderated the association between discrimination and well-being over time such that higher resilience mitigated the detrimental effect of experiencing discrimination on depressive symptoms across time (b = -0.02, p < 0.001). Conclusion Identifying protective features such as resilience can promote the development of culturally tailored interventions to address mental health in the context of discrimination.

Structural racism and homophobia evaluated through social media sentiment combined with activity spaces and associations with mental health among young sexual minority men. Soc Sci Med 2023; 320:115755. [PMID: 36739708 PMCID: PMC10014849 DOI: 10.1016/j.socscimed.2023.115755] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 01/20/2023] [Accepted: 01/29/2023] [Indexed: 02/01/2023]
Abstract
BACKGROUND Research suggests that structural racism and homophobia are associated with mental well-being. However, structural discrimination measures which are relevant to lived experiences and that evade self-report biases are needed. Social media and global-positioning systems (GPS) offer opportunity to measure place-based negative racial sentiment linked to relevant locations via precise geo-coding of activity spaces. This is vital for young sexual minority men (YSMM) of color who may experience both racial and sexual minority discrimination and subsequently poorer mental well-being. METHODS P18 Neighborhood Study (n = 147) data were used. Measures of place-based negative racial and sexual-orientation sentiment were created using geo-located social media as a proxy for racial climate via socially-meaningfully-defined places. Exposure to place-based negative sentiment was computed as an average of discrimination by places frequented using activity space measures per person. Outcomes were number of days of reported poor mental health in last 30 days. Zero-inflated Poisson regression analyses were used to assess influence of and type of relationship between place-based negative racial or sexual-orientation sentiment exposure and mental well-being, including the moderating effect of race/ethnicity. RESULTS We found evidence for a non-linear relationship between place-based negative racial sentiment and mental well-being among our racially and ethnically diverse sample of YSMM (p < .05), and significant differences in the relationship for different race/ethnicity groups (p < .05). The most pronounced differences were detected between Black and White non-Hispanic vs. Hispanic sexual minority men. At two standard deviations above the overall mean of negative racial sentiment exposure based on activity spaces, Black and White YSMM reported significantly more poor mental health days in comparison to Hispanic YSMM. CONCLUSIONS Effects of discrimination can vary by race/ethnicity and discrimination type. Experiencing place-based negative racial sentiment may have implications for mental well-being among YSMM regardless of race/ethnicity, which should be explored in future research including with larger samples sizes.

Young men of color lower on adult attachment anxiety have higher carotid-intima media thickness compared to white young men: The exploration of an unexpected finding. Psychoneuroendocrinology 2022; 143:105825. [PMID: 35689986 DOI: 10.1016/j.psyneuen.2022.105825] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 06/01/2022] [Accepted: 06/02/2022] [Indexed: 11/17/2022]
Abstract
Cardiovascular disease (CVD) remains the number one cause of death among men in the United States. Emerging research demonstrates that socioemotional mechanisms such as adult attachment, or the ways in which individuals are able to form and maintain socioemotional bonds, may impact physical health via alterations in physiological stress functioning. However, there may be key differences in the relation between attachment and physical health by race and sexual orientation. Thus, this study sought to examine the potential moderating effect of race and sexual orientation on the association between adult attachment and carotid-intima media thickness (cIMT), a measure of subclinical cardiovascular disease, among young men. The sample consisted of 72 young men (mean [SD] age = 22.92 [3.23]: 30.6 % identified as White, 30.6 % as Black, and 38.8 % as Other), each of which were surveyed and underwent an ultrasound to measure cIMT. Ordinary Least Squares (OLS) regression was used in order to examine our study hypotheses. We first ran a main effects model to examine adult attachment's (i.e., anxiety and avoidance) association with mean cIMT. We then ran two interaction models with an interaction between race/ethnicity and adult-related attachment and sexual orientation and adult attachment. We found that race significantly moderated the association between attachment-related anxiety and mean cIMT in our study sample. However, we did not find evidence to suggest that race moderated the association between attachment-related avoidance and mean cIMT in our study sample. In comparison to White individuals, Black individuals and those who identified as "Other" race with lower scores on attachment-related anxiety had higher mean cIMT. Additionally, higher scores on attachment-related anxiety were associated with lower mean cIMT among Black and "Other" respondents, but not among White respondents. We did not find evidence to suggest that sexual orientation moderated the association between adult attachment and mean cIMT in our study sample. Our findings suggest that adult attachment anxiety may be protective for young men of color but not for White young men. Future research should utilize longitudinal study designs in order to better understand how adult attachment influences CVD risk among racially/ethnically diverse young men.

Feasibility, Acceptability, and Preliminary Efficacy of an App-Based Meditation Intervention to Decrease Firefighter Psychological Distress and Burnout: A One-Group Pilot Study (Preprint). JMIR Form Res 2021; 6:e34951. [PMID: 35675115 PMCID: PMC9218885 DOI: 10.2196/34951] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 04/15/2022] [Accepted: 04/18/2022] [Indexed: 12/15/2022] Open
Abstract
Background Firefighters are often exposed to occupational stressors that can result in psychological distress (ie, anxiety and depression) and burnout. These occupational stressors have only intensified with the onset of the COVID-19 pandemic and will likely persist in the postpandemic world. Objective To address occupational stressors confronting firefighters, we pilot tested a novel, cost-effective, smartphone app–based meditation intervention created by Healthy Minds Innovations that focused on mindfulness (awareness) training along with practices designed to cultivate positive relationships (connection), insight into the nature of the self (insight), and a sense of purpose in the context of challenge (purpose) with a sample of professional firefighters from a large metropolitan area in southwestern United States. Methods A total of 35 participants were recruited from a closed online group listserv and completed the self-guided 10-unit meditation app over the course of 10 days, at 1 unit per day. We assessed anxiety symptoms, depression symptoms, burnout, and negative affect as well as saliva diurnal cortisol rhythm, an objective indicator of stress-related biology, before and after use of the meditation app. Results This study demonstrated the meditation app was both feasible and acceptable for use by the majority of firefighters. We also found significant reductions in firefighters’ anxiety (P=.01), burnout (P=.05), and negative affect (P=.04), as well as changes in cortisol diurnal rhythm, such as waking cortisol (P=.02), from before to after use of the meditation app. Conclusions Our study findings call for future research to demonstrate the efficacy of this meditation app to reduce psychological distress and burnout in firefighters.

Assessing Perceptions of Broad Consent Concerning Biological Specimen Collection in a Cohort of Young Sexual Minority Men. ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:3313-3321. [PMID: 34617188 PMCID: PMC8493942 DOI: 10.1007/s10508-021-01964-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 02/16/2021] [Accepted: 02/18/2021] [Indexed: 06/13/2023]
Abstract
The use of broad consent to store human biospecimens to be used in future research studies has increased over the years. However, it is currently unknown how young sexual minority men (YSMM) perceive broad consent in these specific types of studies. Therefore, in this study we aimed to determine the extent to which YSMM are comfortable with providing broad consent concerning their identifiable biological specimens to a variety of entities, including external researchers and pharmaceutical companies and to examine the relationship between mistrust based on racial/ethnic identity or sexual orientation and attitudes toward broad consent. YSMM (N = 239) ages 24-27 years were recruited from a prospective cohort study in New York City in 2018 to complete a survey assessing attitudes about the use of broad consent concerning biospecimens for secondary research. We found that YSMM were most willing to provide broad consent to the researcher from the study they were enrolled in (85.3%), other researchers within the same university (82.4%), and researchers at other universities (74.5%). Participants were least willing to provide broad consent to government organizations (64.4%) and pharmaceutical companies (53.8%). Further, we found that medical mistrust based on racial/ethnic identity or sexual orientation was associated with attitudes toward the use of broad consent. Research institutions should consider modifying consent procedures around the use of broad consent in order to maximize recruitment and retention, especially among minority populations.

Abstract
BACKGROUND Exposure to sexual orientation-related discrimination among sexual minorities may lead to elevated levels of C-reactive protein (CRP) as compared to their heterosexual counterparts. However, little is known about factors that may buffer the association between discrimination and CRP among sexual minorities versus heterosexuals. The current study examined if the association between discrimination, sexual orientation, and CRP differed across levels of social support from one's father/father-figure or mother/mother-figure between sexual minorities and heterosexuals. METHODS Data came from Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health). The sample sizes for father support and mother support was 3167 and 3575, respectively. Participants ranged in age from 24 to 33 years. Stratified linear regression models examined if father and mother support moderated the association between discrimination and CRP among sexual minorities and heterosexuals. RESULTS Father support significantly moderated the association between discrimination and CRP among sexual minorities but not heterosexuals. Sexual minorities with higher father support and who experienced discrimination had lower CRP as compared to those with lower father support and who experienced discrimination. Mother support did not moderate the association between discrimination and CRP among either sexual minorities or heterosexuals. CONCLUSION Father support may mitigate the negative effects of stress from discrimination on CRP among sexual minorities. Future research should further examine the potential differential role that father support may play in reducing cardiovascular risk among sexual minorities versus heterosexuals who experience discrimination.

Abstract
We conducted a mixed-methods study to identify factors that influence transitions in attachment style between childhood and adulthood among 28 young Black gay and bisexual men (YBGBM) in the United States. We used a phenomenological approach to data integration, with the major component to the results being garnered from the qualitative interviews. We organized our results by four attachment transition groups: stable secure (secure attachment in childhood and young adulthood), stable insecure (insecure attachment in childhood and young adulthood), secure to insecure (secure in childhood and insecure in adulthood) and insecure to secure (insecure in childhood and secure in adulthood). Within each of the typologies, two major themes emerged: social support and religion. Generally, transitions from secure to insecure attachment were related to experiences of perceived rejection by a parental figure during adolescence that corresponded with sexual orientation disclosure. Transitions from insecure to secure attachment appeared to be related to the absence of an attachment figure early in life, but with the acquisition of an attachment figure during early to late adolescence. The findings from our study suggest a need for attachment-based approaches to social support interventions, as well as for an increased understanding of social and cultural factors that impact attachment changes among practitioners who use attachment-based therapy models for YBGBM.

Abstract
Exposure to violence during adolescence is associated with increased risk behaviors and mental health problems in adulthood. Friendship attachment during adolescence may, however, mitigate the negative effects of exposure to violence on trajectories of depression and anxiety in young adulthood. In this study, we used growth curve modeling to examine associations between exposure to violence and mental health outcomes, followed by multi-group analyses with friendship attachment as the moderator. The sample was drawn from a longitudinal study (12 waves; 1994-2012) of 676 (54% female) urban high school students. We found strong positive associations between exposure to violence during adolescence and later self-reported depressive and anxiety symptoms. Notably, securely attached adolescents reported faster decreases in mental health symptoms as a function of violence relative to their insecurely attached peers as they transitioned into adulthood.

Abstract
Objective:To examine self-reported prevalence data for migraine among adolescent Canadians and to explore how reported migraine treatment varies by age.Methods:We analyzed the microdata files of the Canadian National Population Health Survey (1996-1997). Respondents reported whether they had “migraine headaches diagnosed by a health professional”. They also reported whether they received “any treatment or medication for migraine headaches”, with treatments subdivided into drug, diet or “other”.Results:99.9% of 173,216 eligible respondents reported whether they had migraine headaches. Migraine was reported by 2.4% of Canadian youth aged 12-14 years and by 5.0% of 15-19 year-olds compared to 7.2% of adults aged 20 years of age (p< 0.0001, chi-square). Active treatment was used by 51.0% - higher by females (53.1%) than males (44.7%) (p<0.0001 chi-square). Treatment was used by 45.1% of 12-14 year-olds, by 45.7% of 15-19 year-olds and by 51.5% of those 20 years (p=0.0027). The nature of the active treatment choice (drug, diet or other) did not significantly vary within the age groups studied.Conclusion:We present robust estimates of self-report diagnosed migraine prevalence, derived from a large nationally representative population survey. Estimates of the prevalence of active treatment for migraine provide insight into the burden of migraine within this population.

Abstract
OBJECTIVE To validate our previous estimates of the prevalence of frequent headache and associated factors in a new sample of 12- to 13-year-old adolescent Canadians, and to explore if estimates of the prevalence of frequent headache and associated factors remain stable within the original cohort after a two-year interval. METHODS We analyzed the self-administered questionnaire microdata files of the National Longitudinal Survey of Children and Youth (NLSCY: 1998-1999). 1694 respondents representing 724,400 youth aged 12 to 13 years were used to validate the prevalence in our initial estimates. From the initial cohort, 1764 respondents representing 819,600 youth, now aged 14 to 15 years, were used to examine whether frequent headache prevalence or associated factors had changed in the intervening two years. RESULTS Among the analyzed individuals, 26.3% of 12- to 13-year olds and 31.2% of 14- to 15-year olds reported frequent headaches of "about once a week" or more often (P= .001). Our previous study of the NLSCY: 1996-1997 found a prevalence of 26.6% in 12- to 13-year olds. We previously identified 22 risk factors, of which 15 were replicated and one proxy was available within this iteration of the survey. For the 12- to 13-year olds, 14/16 were associated (P < .01, chi-square) with frequent headaches. For the initial cohort, now 14- to 15-year olds, 15/16 risk factors remained associated (P < .01, chi-square) with an increased risk of headaches. CONCLUSIONS Our estimates of frequent headache prevalence are reliable and consistent in two large nationally representative cohorts of 12- to 13-year olds. In the first of these groups there was an increase in prevalence over 2 years as adolescence progresses. Our identified risk factors for frequent headaches have been validated within another cohort and are maintained as the cohort ages.

Abstract
OBJECTIVE To explore the associated factors for frequent headache among young adolescent Canadians. METHODS We analyzed the self-administered questionnaire microdata files of the National Longitudinal Survey of Children and Youth (NLSCY: 1996 to 1997). Two thousand and ninety respondents representing 793,100 Canadian youth aged 12 to 13 years were asked how often they had headaches in the previous 6 months. RESULTS Of the 2090 adolescents, 1998 (96%) responded. Frequent headaches of "about once a week" or more often were reported by 26.6% of them aged 12 to 13 years (95% CI: 24.2, 28.6). Frequent headaches appear to be associated with a plethora of risk factors germane to the life experience of these young adolescents. All factors were significant at P <.0001 by chi-square analysis and can be loosely categorized as school-related, lifestyle-related, or involving mental health. A multivariate Classification and Regression Tree (CART) analysis models frequent headaches on a depression scale, a self-esteem scale, and ever having smoked, with 60% sensitivity, and 65% specificity. CONCLUSIONS The NLSCY reveals a remarkable insight into headache frequency and the life experience of Canada's young adolescents with frequent headaches.

Abstract
Drooling is problematic for some neurologically impaired children. Botulinum toxin A injection to salivary glands has effectively reduced drooling in adults but has only recently been used to treat children. This was a preliminary study to determine the efficacy and safety of botulinum toxin in children. Children identified as having severe daily drooling were enrolled. The preinjection assessment included measurement of the amount and frequency of drool. Each parotid gland was injected with 5 U of botulinum toxin A. Follow-up was for a minimum of 16 weeks. Nine children were enrolled, 4-17 years of age. All children had moderate or severe mental retardation. At week 4, all patients had a reduced drooling frequency and eight of nine patients had a reduction in the weight of saliva. Overall, five of nine parents (55%) deemed the treatment successful. This preliminary study demonstrates that botulinum toxin A is a relatively effective treatment for some children with significant drooling without serious side effects.

Abstract
BACKGROUND There is little data available on the acceptability to parents, of alternate methods of delivering care to their children. This pilot study explored parents' perceptions of conventional clinic visits and their attitudes to potential alternative methods of delivering care. METHODS Questionnaires were completed by the families of 200 consecutive children before and after a visit to a tertiary-care Pediatric Neurology Clinic in Nova Scotia, Canada. RESULTS Responses were received from 172 (86%) for the first questionnaire and 138 (69%) for the second. There were 59 new referrals, 76 follow-up visits and 39 were seen because of new concerns. Visiting the clinic resulted in school absenteeism for 85% of the children and lost pay for 19% of the parents. Telephone, video conference or replacement of the physician by a nurse practitioner were acceptable alternate methods of assessment for only 10%. The only factor which was associated with willingness to accept telephone as an assessment modality was an initial opinion that the visit was unnecessary. CONCLUSION Escalating health care costs and limited specialist availability demand consideration of alternate methods of care delivery. Although adults seem comfortable with care outside the usual clinic setting, there is little data for the pediatric setting. The responses from the parents attending our clinic, indicate that families were happy with services offered in the conventional clinic. In contrast, only 10% found potential alternate methods acceptable. These opinions must be considered in the design of new methods of caring for children.

Abstract
OBJECTIVE The aim of this study was to estimate population based incidence rates for infantile spasms (IS) and to study our clinical impression that the incidence of IS has recently decreased in the Canadian Provinces of Nova Scotia and Prince Edward Island. METHODS Birth cohorts from 1978 to 1998, identified through the hospital health records, EEG records and physician computerized databases, were followed for two years for the development of IS. Disease incidence rates were calculated using denominators derived from Statistics Canada's reported annual live birth rates. RESULTS The inclusion criteria for IS were fulfilled by 75 patients. The overall incidence of IS was 30.7/100,000 live births (95% Cl 24.3, 38.8). Etiologic classification was symptomatic for 51 cases (68%), cryptogenic for 18 (24%), and idiopathic in six children (8%). Although there were more males (N=44) than females (N=31), the incidence rates were similar. There was a marked variability in annual and five-year incidence rates. CONCLUSIONS Although the clinical characteristics of our patients were similar to other reported IS populations, the instability in IS incidence rates indicates a need for caution in interpreting smaller IS epidemiologic studies.

Abstract
Krabbe's disease is characterized by normal neonatal development with subsequent regression and profound, medically intractable irritability. Two female infants presented at 5 months of age with increasing irritability, abnormal motor control, and developmental regression. Investigations confirmed the diagnosis of Krabbe's disease. Maximal treatment of gastroesophageal reflux and nitrazepam 0.1 mg/kg by mouth three times daily were unsuccessful in controlling irritability. Morphine was initiated and titrated to 0.06 mg/kg by mouth every 6 hours in Patient 1 and 0.1 mg/kg by mouth every 8 hours in Patient 2, resulting in remarkably successful control of irritability. The diagnosis of Krabbe's disease is devastating for families and is compounded by the marked irritability. Management is difficult, but in these two infants, irritability was successfully controlled with low-dose morphine.

Abstract
BACKGROUND AND PURPOSE Development of gross motor function in children with cerebral palsy (CP) has not been documented. The purposes of this study were to examine a model of gross motor function in children with CP and to apply the model to construct gross motor function curves for each of the 5 levels of the Gross Motor Function Classification System (GMFCS). SUBJECTS A stratified sample of 586 children with CP, 1 to 12 years of age, who reside in Ontario, Canada, and are known to rehabilitation centers participated. METHODS Subjects were classified using the GMFCS, and gross motor function was measured with the Gross Motor Function Measure (GMFM). Four models were examined to construct curves that described the nonlinear relationship between age and gross motor function. RESULTS The model in which both the limit parameter (maximum GMFM score) and the rate parameter (rate at which the maximum GMFM score is approached) vary for each GMFCS level explained 83% of the variation in GMFM scores. The predicted maximum GMFM scores differed among the 5 curves (level I=96.8, level II=89.3, level III=61.3, level IV=36.1, and level V=12.9). The rate at which children at level II approached their maximum GMFM score was slower than the rates for levels I and III. The correlation between GMFCS levels and GMFM scores was (.91. Logistic regression, used to estimate the probability that children with CP are able to achieve gross motor milestones based on their GMFM total scores, suggests that distinctions between GMFCS levels are clinically meaningful. CONCLUSION AND DISCUSSION Classification of children with CP based on functional abilities and limitations is predictive of gross motor function, whereas age alone is a poor predictor. Evaluation of gross motor function of children with CP by comparison with children of the same age and GMFCS level has implications for decision making and interpretation of intervention outcomes.
