This paper summarizes the arguments and counter-arguments in the scholarly debates on transformations in healthcare budgeting that should consider the differentiated regional vulnerability in responding to the pandemic. The primary purpose of the study is to identify priorities for local health development programs. The urgency of solving this problem is that the pandemic has revealed the unprecedented unpreparedness of the health care system to respond effectively to challenges; also, hidden problems accumulated during the last decades, which increase the emerging risks. The study is carried out in the following logical sequence: 1) collection, processing, and analysis of statistical data; 2) conducting a cluster analysis for group regions by vulnerability to different classes of diseases; 3) conducting correlation and regression analysis to compare the effects of the COVID-19 pandemic (cases and deaths) and the state of the region; 4) selection of the most significant features of the vulnerability of the region; 5) designing the matrix of the choice of priorities for financing targeted programs in the field of health care. Methodological tools of the study were methods of correlation and regression analysis, cluster analysis, testing for autocorrelation by Darbin — Watson method, sigma limited parameterization to identify the most significant coefficients. The method is tested for 25 regions of Ukraine (including Kyiv), as they can serve as pilots for other regions with similar demographic and economic characteristics. The article presents the results of an empirical analysis of the readiness of regions for critical conditions, such as COVID-19. Identifying such readiness and appropriate distribution of regions by disease classes allows to make decisions in financing and budgeting and improve the quality of health care. Узагальнено аргументи і контраргументи в межах наукової дискусії з питання зміни бюджетної оптимізації в галузі охорони здоров’я з урахуванням диференційованої регіональної вразливості від наслідків пандемії. Основною метою проведеного дослідження є визначення пріоритетних напрямів розвитку місцевих програм розвитку в галузі охорони здоров’я. Актуальність розв’язання наукової проблеми полягає в тому, що пандемія виявлила неготовність системи охорони здоров’я реагувати ефективно на виклики, окрім того, виявила приховані проблеми, закумульовані протягом останнього часу, яку підвищують ризики, що з’являться в майбутньому. Дослідження питання виявлення пріоритетних напрямів розвитку програм у галузі охорони здоров’я здійснено в такій логічній послідовності: 1) збір, обробка та аналіз масиву статистичних даних; 2) проведення кластерного аналізу для групування регіонів за вразливістю до різних класів хвороб; 3) проведення кореляційно-регреійного аналізу для зіставлення наслідків впливу пандемії COVID-19 і стану досліджуваної галузі в регіонах; 4) виділення найбільш впливових ознак на вразливість регіону; 5) запропонована матриця вибору пріоритетів фінансування цільових програм у сфері охорони здоров’я. Методичним інструментарієм проведеного дослідження стали методи кореляційно-регресійного аналізу, кластерного аналізу, перевірка на наявність автокореляції методом Дарбіна — Уотсона, проведена сигма обмежена параметризація для виявлення найбільш значущих коефіцієнтів. Об’єктом дослідження обрано 25 регіонів України (включно із м. Києвом), оскільки вони можуть служити пілотними для інших регіонів, схожих за демографічними та економічними характеристиками. Представлено результати емпіричного аналізу готовності регіонів до критичних станів, таких як COVID. Вииявлення такої готовності та відповідний розподіл регіонів за класами хвороб дозволить знайти оптимальний шлях для перерозподілу фінансових ресурсів і поліпшення якості надання медичної допомоги.

- Abstract
Objectives: The aim of this study was to explore oral health experiences and priorities in a diverse group of adults aged over 60 in North West England, an area with high oral health inequality., Methods: Participants were selected using purposive sample from multiple settings across the North West: community, primary dental care and residential care home. Data were collected between October 2018 and March 2019 and involved eight focus groups and three individual interviews with a total of 47 participants. The data were analysed using thematic analysis., Results: Four key themes were identified. The first was issues important to people over 60, which included the appearance of one's teeth, communication, continuity of care and the treatment experience. These were informed by two further themes, past experiences of treatment, which were not always favourable, and perceived barriers, such as accessing NHS dentistry, cost, physical access and oral care in institutional settings. The fourth, connected theme focussed on how oral healthcare messages for different audiences should be disseminated., Conclusions: There are shortfalls in the provision of oral healthcare to older adults in the UK. Communication and continuity of care with a trusted oral healthcare provider are key priorities for this population. However, our participants felt that current public provision of dental services is not meeting their needs., (© 2023 The Authors.

- Abstract
We investigated the anti-ulcer activity of ethanol extracts of Polygonum cognatum on indomethacin induced gastric damage in rats. We evaluated the number of ulcer areas, oxidant and antioxidant parameters as well as histopathologic features in rat stomach. We measured the total antioxidant status of P. cognatum in concentrations from 1.56-100 mg/ml. P. cognatum extract inhibited indomethacin induced ulcer formation with an effect similar to a 20 mg/kg dose of the standard anti-ulcer drug, esomeprazole. All doses of P. cognatum extract exhibited positive effects on oxidative stress markers and histopathological features in the stomach tissue of rats. We suggest that the antioxidant activity of P. cognatum extract may be responsible for its gastroprotective effect and that P. cognatum extract may be a useful gastroprotective agent.

- Abstract
Purpose: Surgical removal of third molars carries morbidity and significantly affects patients' quality-of-life. This study aims to investigate whether administration of low-level laser therapy (LLLT) is effective in reducing postoperative morbidity in patients undergoing surgical removal of mandibular third molars compared with placebo., Material and Methods: A systematic review and meta-analysis involving a comprehensive search strategy implemented across 5 electronic databases. This was supplemented by hand searching and contacting international experts and grey literature. Titles, abstracts, and full articles were scrutinized for studies meeting the inclusion criteria. All randomized controlled trials comparing treatment group of LLLT with a placebo control group were eligible for inclusion. The outcomes variables were postoperative pain, swelling, and trismus. Risk of bias and methodological quality assessment was carried out. We pooled data statistically, and meta-analyses were carried out using a random-effects model., Results: Seventeen randomized controlled trials were included in this systematic review, all of which were considered to have a low risk of bias. Participants, aged 13 to 70 years, and 35% women, totaled 1064. Meta-analyses found significant reductions in standardized mean differences (SMDs) in swelling at day 2 and day 7 postoperatively (SMD, -0.611; 95% confidence interval, -0.968, -0.234 and SMD, -0.532; 95% confidence interval, -0.795, -0.269). There were nonsignificant reductions in SMD in pain and trismus at day 2 and day 7 postoperatively., Conclusions: LLLT significantly reduces swelling after extraction of mandibular third molars compared with placebo. LLLT has not shown to reduce postoperative pain and trismus. LLLT does not cause adverse effects. There is currently insufficient evidence available, to promote the investment in LLLT vs the net clinical benefit. Randomized controlled trials with larger sample size and standardized study design and outcome measures are required, to make definitive recommendations to clinicians on its use on patients., (Copyright © 2020 American Association of Oral and Maxillofacial Surgeons.

- Abstract
Objectives The objective of this systematic review was to evaluate the success of endocrown restorations on molars in comparison with endocrown restorations on premolars.Registration number The methodology for this review is registered with the PROSPERO database (CRD42019149543).Data sources Medline, Embase, Dentistry & Oral Sciences Source and Cochrane CENTRAL were searched through January 2020, supplemented with hand searching of additional relevant journals.Data selection and data extraction Two independent reviewers screened studies against predefined inclusion criteria and extracted data.Data analysis Narrative analysis was carried out and random-effects meta-analysis was performed where possible.Results Out of the selected eight studies, reported success rate of endocrown restoration in molars varied from 72.73% to 99.57% and in premolars ranged from 68.75% to 100%, with a follow-up range of 3-19 years. The pooled odds ratio and 95% confidence intervals for failure rates in molars compared to premolars in four studies selected for meta-analysis were 1.096 (95% CI: 0.280, 4.292).Conclusions These findings showed similar success rates and no difference in the rate of endocrown failures between molars and premolars, thus suggesting that premolars may be considered suitable candidates for endocrowns. However, the findings should be interpreted with caution due to methodological limitations of the included studies. Further better quality and specifically designed controlled trials directly comparing the clinical performance of endocrowns on molars and premolars are required.

- Abstract
Background: Childhood asthma is a common condition whose prevalence is changing. We hypothesized that the relationship between asthma and associated risk factors has changed over a 50-year period., Methods: An ecological study design was used. Children aged 8-13 attending schools in Aberdeen city were surveyed on seven occasions between 1964 and 2014. The following were determined: history of asthma, history of eczema, parental smoking, parental asthma, sex and socio-economic status. Analysis was by a structural change model with two knots. The outcome reported was the change in odds ratio between asthma and a given risk factor during a given period., Results: There were 23,241 questionnaires distributed and 17,439 returned (75%). The odds ratio (OR) for a child with asthma to have eczema increased between 1989 and 1999 by 1.031 [95% CI 1.028, 1.035] and by 1.042 between 2004 and 2014 [1.038, 1.047]. The OR for a child with asthma to have a parent who smoked rose by 1.032 [1.028, 1.036] between 1989 and 1999 and by 1.043 [1.038, 1.047] between 2004 and 2014), and to have a parent with asthma (1.027 [1.022, 1.031] for 1994-99 and 1.042 [1.037, 1.048] for 2004-2014). The OR for a child with asthma being male, but not and being from the most deprived communities, rose between 1989-1999 and 2004-2014., Conclusions: The relationship between asthma prevalence and particular risk factors changed over the 50-year period of study, and this might reflect changes in children's environment and/or susceptibility., (© 2016 John Wiley & Sons A/S.

- Abstract
Background: Evidence from longitudinal population-based studies relating occupational exposure to the full range of different forms of airborne pollutants and lung function and airway obstruction is limited., Objective: To relate self-reported COPD and lung function impairment to occupational exposure to different forms of airborne chemical pollutants in individuals who did not have childhood wheeze., Methods: A prospective cohort study was randomly selected in 1964 at age 10-15 years and followed up in 1989, 1995, 2001 and 2014 (aged 58-64) by spirometry and respiratory questionnaire. Occupational histories were recorded in 2014 and occupational exposures assigned using an airborne chemical job exposure matrix. The risk of COPD and lung function impairment was analyzed in subjects, who did not have childhood wheeze, using logistic and linear regression and linear mixed effects models., Results: 237 subjects without childhood wheeze (mean age 60.6 years, 47% male) were analyzed. There was no association between any respiratory outcomes and exposure to gases, fibers, mists or mineral dusts and no consistent associations with exposure to fumes. Reduced FEV
1 was associated with longer duration (years) of exposure to any of the six main pollutant forms - vapors, gases, dusts, fumes, fibers and mists (VGDFFiM) with evidence of a dose-response relationship (p-trend=0.004). Exposure to biological dusts was associated with self-reported COPD and FEV1 25-75% (adjusted regression coefficients [95% CIs] -9.11 [-17.38, -0.84] respectively). Exposure to vapors was associated with self-reported COPD and FEV 1 1 and FEF 25-75% associated with exposure to biological dusts or vapors., Conclusions: People with no history of childhood wheezing who have been occupationally exposed to biological dusts or vapors or had longer duration of lifetime exposure to any VGDFFiM are at a higher risk of reduced lung function at age 58-64 years. Occupational exposure to biological dusts or vapors also increased the risk of self-reported COPD., (Copyright © 2016 Elsevier Inc. All rights reserved.)- Published

- Abstract
Background: There are few prospective studies that relate the development of adult respiratory disease with exposure to occupational asthmagens., Objective: To evaluate the risk of adult onset wheeze (AOW) and obstructive lung function associated with occupational exposures over 50years., Methods: A population-based randomly selected cohort of children who had not had asthma or wheezing illness, recruited in 1964 at age 10-15years, was followed-up in 1989, 1995, 2001 and 2014 by spirometry and respiratory questionnaire. Occupational histories were obtained in 2014 and occupational exposures determined with an asthma-specific job exposure matrix. The risk of AOW and lung function impairment was analysed in subjects without childhood wheeze using logistic regression and linear mixed effects models., Results: All 237 subjects (mean age: 61years, 47% male, 52% ever smoked) who took part in the 2014 follow-up had completed spirometry. Among those who did not have childhood wheeze, spirometry was measured in 93 subjects in 1989, in 312 in 1995 and in 270 subjects in 2001 follow-up. For longitudinal analysis of changes in FEV1 between 1989 and 2014 spirometry records were available on 191 subjects at three time points and on 45 subjects at two time points, with a total number of 663 records.

- Abstract
Rationale: Cohort studies suggest that airflow obstruction is established early in life, manifests as childhood asthma and wheezy bronchitis, and continues into early adulthood. Although an association between childhood asthma and chronic obstructive pulmonary disease (COPD) in later life has been demonstrated, it is unclear if childhood wheezy bronchitis is associated with COPD., Objectives: To investigate whether childhood wheezy bronchitis increases the risk of COPD in the seventh decade., Methods: A cohort of children recruited in 1964 at age 10 to 15 years, which was followed up in 1989, 1995, and 2001, was followed up again in 2014 when at age 60 to 65 years. Discrete time-to-event and linear mixed effects models were used., Measurements and Main Results: FEV1 and FVC were measured. COPD was defined as post-bronchodilator FEV1/FVC <0.7. Childhood wheezing phenotype was related to 1989, 1995, 2001, and 2014 spirometry data. Three hundred thirty subjects, mean age 61 years, were followed up: 38 with childhood asthma; 53 with childhood wheezy bronchitis; and 239 control subjects (of whom 57 developed adulthood-onset wheeze between ages 16 and 46 yr). In adjusted multivariate analyses, childhood asthma was associated with an increased risk of COPD (odds ratio, 6.37; 95% confidence interval, 3.73-10.94), as was childhood wheezy bronchitis (odd ratio 1.81; 95% confidence interval, 1.12-2.91). The COPD risk increased with childhood asthma, and wheezy bronchitis was associated with reduced FEV1 that was evident by the fifth decade and not an accelerated rate of FEV1 decline. In contrast, adulthood-onset wheeze was associated with accelerated FEV1 decline., Conclusions: Childhood wheezy bronchitis and asthma are associated with an increased risk of COPD and reduced ventilatory function.

- Abstract
This small study investigated house dust mite (HDM) allergen levels in cars and their owners' homes in north-east Scotland. Dust samples from twelve households and cars were collected in a standardised manner. The dust samples were extracted and measured for the Dermatophagoides group 2 allergens (Der p 2 and Der f 2) and total soluble protein. Allergen levels at homes tended to be higher than in the cars, but not significantly. However, they significantly correlated with paired car dust samples expressed either per unit weight of dust or soluble protein (rho=0.657; p=0.02 and 0.769; p=0.003, respectively). This points to house-to-car allergen transfer, with the car allergen levels largely reflecting levels in the owner's home. Car HDM allergen levels were lower than those reported in Brazil and the USA. Twenty-five percent of the houses and none of the cars had allergen levels in dust greater than 2000 ng g(-1). This value is often quoted as a threshold for the risk of sensitisation, although a number of studies report increased risk of sensitisation at lower levels. This small study does not allow for characterisation of the distribution of HDM allergen in vehicles in this geographic area, or of the likely levels in other warmer and more humid areas of the UK. Cars and other vehicles are an under-investigated micro-environment for exposure to allergenic material.

- Abstract
Volatile organic compounds (VOCs) are ubiquitous domestic pollutants. Their role in asthma/allergy development and exacerbations is uncertain. This systematic review investigated whether domestic VOC exposure increases the risk of developing and/or exacerbating asthma and allergic disorders. We systematically searched 11 databases and three trial repositories, and contacted an international panel of experts to identify published and unpublished experimental and epidemiological studies. 8455 potentially relevant studies were identified; 852 papers were removed after de-duplication, leaving 7603 unique papers that were screened. Of these, 278 were reviewed in detail and 53 satisfied the inclusion criteria. Critical appraisal of the included studies indicated an overall lack of high-quality evidence and substantial risk of bias in this body of knowledge. Aromatics (i.e. benzenes, toluenes and xylenes) and formaldehyde were the main VOC classes studied, both in relation to the development and exacerbations of asthma and allergy. Approximately equal numbers of studies reported that exposure increased risks and that exposure was not associated with any detrimental effects. The available evidence implicating domestic VOC exposure in the risk of developing and/or exacerbating asthma and allergy is of poor quality and inconsistent. Prospective, preferably experimental studies, investigating the impact of reducing/eliminating exposure to VOC, are now needed in order to generate a more definitive evidence base to inform policy and clinical deliberations in relation to the management of the now substantial sections of the population who are either at risk of developing asthma/allergy or living with established disease., (Copyright ©ERS 2015.)

- Abstract
Over the past decades, the prevalence of asthma, allergic disease and atopy has increased significantly and in parallel with the increased use of products and materials emitting volatile organic compounds (VOCs) in the indoor environment. The purpose of this review is to examine the evidence of the relationship between quantitatively measured domestic exposure to VOCs and allergic diseases and allergy in children and adults. Sources, potential immune-inflammatory mechanisms and risks for development and severity of asthma and allergy have been addressed. Available evidence is based on studies that have mainly used observational designs of variable quality. Total, aromatic, aliphatic, microbial VOCs and aldehydes have been the most widely investigated VOC classes, with formaldehyde being the most commonly examined single compound. Overall, the evidence is inadequate to draw any firm conclusions. However, given indicative evidence from a few high-quality studies and significant potential for improvements in asthma outcomes in those with established disease, there is a need to consider undertaking further investigation of the relationship between domestic VOC exposure and asthma/allergy outcomes that should encompass both high-quality, robust observational studies and ultimately clinical trials assessing the impact of interventions that aim to reduce VOC exposure in children and adults with asthma.

- Abstract
The increase in asthma and allergies has been attributed to declining exposure to environmental microorganisms. The main source of these is soil, the composition of which varies geographically and which is a major component (40-45%) of household dust. Our hypothesis-generating study aimed to investigate associations between soil components, respiratory health and allergy in a Scottish birth cohort. The cohort was recruited in utero in 1997/8, and followed up at one, two and five years for the development of wheezing, asthma and eczema. Lung function, exhaled nitric oxide and allergic sensitization were measured at age five in a subset. The Scottish Soils Database held at The James Hutton Institute was linked to the birth cohort data by the residential postcode at birth and five years. The soil database contained information on size separates, organic matter concentration, pH and a range of inorganic elements. Soil and clinical outcome data were available for 869, 790 and 727 children at one, two and five years. Three hundred and fifty nine (35%) of children had the same address at birth and five years. No associations were found between childhood outcomes and soil content in the residential area at age five. The soil silt content (2-20 μm particle size) of the residential area at birth was associated with childhood wheeze (adjusted OR 1.20, 95% CI [1.05; 1.37]), wheeze without a cold (1.41 [1.18; 1.69]), doctor-diagnosed asthma (1.54 [1.04; 2.28]), lung function (FEV1: beta -0.025 [-0.047;-0.001]) and airway inflammation (FENO: beta 0.15 [0.03; 0.27]) at age five, but not with allergic status or eczema. Whilst residual confounding is the most likely explanation for the associations reported, the results of this study lead us to hypothesise that early life exposure to residential soil silt may adversely influence childhood respiratory health, possibly because of the organic components of silt., (© 2013 Elsevier B.V.

- Abstract
Background: Exposure to flour/flour constituents is a leading cause of occupational asthma. Paternal occupational exposure to flour has been associated with increased likelihood of childhood asthma, raising the possibility of para-occupational exposure whereby family members are exposed to sensitizers 'taken home' on contaminated skin/clothing., Objective: To establish whether workplace contamination of skin/clothing with wheat flour allergen (WFA) and fungal α-amylase (FAA) is associated with increased levels of these allergens in bakers' homes., Methods: Bakeries in north-east Scotland were invited to participate. Control subjects were recruited from University of Aberdeen staff and students. Exposure assessment was carried out in bakeries, bakers' cars and the homes of bakers and controls using surface wipe and vacuum sampling; samples were analyzed for total protein, FAA and WFA., Results: 164 wipe samples and 49 vacuum samples were collected from 38 bakers (from 5 bakeries) and 10 controls. Compared to non-bakers, bakers had higher median levels of WFA and FAA in house vacuum samples; the difference was statistically significant for WFA/total protein (515.8×10(-6) vs. 163.7×10(-6), p=0.031), FAA/total protein ratios (1.45×10(-6) vs. 0.04×10(-6), p<0.001) and FAA loading (median 1.2 pg/cm(2) vs. 0.1 pg/cm(2), p<0.001) with workplace exposure-home contamination relationships between bakers with higher and lower workplace contamination. We found positive correlations between WFA contamination of the bakers' foreheads and cars (r(s)0.57, p=0.028), foreheads and houses (r(s)0.46, p=0.025), shoes and houses (r(s)0.45, p=0.029); and between FAA contamination of shoes and houses (r(s)0.46, p=0.023), and cars and houses (r(s)0.70, p=0.008). There was no evidence of bakers using work-sourced flour for domestic baking., Conclusions: This work demonstrates pathways for 'take home' exposure of occupationally sourced flour. Taken with our previous work, showing that bakers' children are more likely to have asthma, this supports the need for further investigation to establish whether 'take home' of occupationally sourced flour is widespread with health consequences., (Copyright © 2012 Elsevier Ltd.

- Abstract
Objectives: Most of the evidence on agreement between self- and proxy-reported occupational data comes from interview-based studies. The authors aimed to examine agreement between women's reports of their partner's occupation and their partner's own description using questionnaire-based data collected as a part of the prospective, population-based Avon Longitudinal Study of Parents and Children., Methods: Information on present occupation was self-reported by women's partners and proxy-reported by women through questionnaires administered at 8 and 21 months after the birth of a child. Job titles were coded to the Standard Occupational Classification (SOC2000) using software developed by the University of Warwick (Computer-Assisted Structured Coding Tool). The accuracy of proxy-report was expressed as percentage agreement and kappa coefficients for four-, three- and two-digit SOC2000 codes obtained in automatic and semiautomatic (manually improved) coding modes. Data from 6016 couples at 8 months and 5232 couples at 21 months postnatally were included in the analyses., Results: The agreement between men's self-reported occupation and women's report of their partner's occupation in fully automatic coding mode at four-, three- and two-digit code level was 65%, 71% and 77% at 8 months and 68%, 73% and 76% at 21 months. The accuracy of agreement was slightly improved by semiautomatic coding of occupations: 73%/73%, 78%/77% and 83%/80% at 8/21 months respectively. While this suggests that women's description of their partners' occupation can be used as a valuable tool in epidemiological research where data from partners are not available, this study revealed no agreement between these young women and their partners at the two-digit level of SOC2000 coding in approximately one in five cases., Conclusion: Proxy reporting of occupation introduces a statistically significant degree of error in classification. The effects of occupational misclassification by proxy reporting in retrospective occupational epidemiological studies based on questionnaire data should be considered.

- Abstract
The present birth cohort study investigated whether or not childhood wheeze and asthma are associated with parental exposure to occupational sensitisers that cause asthma. Parental occupation, from the Avon Longitudinal Study of Parents and Children (ALSPAC), was related to wheeze, asthma, ventilatory function, airway responsiveness and atopic sensitisation in children aged 0-102 months. Occupation was recorded for 11,193 mothers and 9,473 fathers antenatally, and for 4,631 mothers and 5,315 fathers post-natally. Childhood respiratory outcomes were not associated with parental occupational exposure to diisocyanates, glues/resins, dyes, animal dust, solder, enzymes and wood dust. Maternal post-natal occupational exposure to latex and/or biocides/fungicides increased the likelihood of childhood wheeze and asthma. High levels of latex or biocide/fungicide exposure were associated with an OR (95% CI) of 1.26 (1.07-1.50) and 1.22 (1.02-2.05), respectively, for wheezing up to 81 months. Combined maternal latex and biocide/fungicide exposure increased the likelihood of childhood wheeze (1.22 (1.03-1.43)) and asthma. High paternal occupational flour dust exposure was associated with an increased likelihood of wheeze after 30 months (2.31 (1.05-5.10)) and asthma by 91 months (3.23 (1.34-7.79)). Maternal occupational exposure to latex and/or biocides and paternal exposure to flour dust increases the risk of childhood asthma. Further studies in this area are justified.

- Abstract
To compare risk factors for wheezy bronchitis (WB) and multi-trigger wheeze (MTW) in pre-pubertal children along the spectrum of disease severity. Cross-sectional survey of children aged 7-12 yr in Aberdeen city primary schools in 2004 using parent-completed questionnaires as used in surveys in 1964, 1989, 1994, and 1999. Children were grouped into five categories: no wheeze in the past three years, non-severe wheeze triggered only by a cold (non-severe WB), non-severe wheeze triggered by other factors (non-severe MTW), severe WB, or severe MTW. Severe wheeze was defined as greater than four wheezing attacks, greater than or equal to one disturbed night per week, or speech limitation in the last 12 months. Questionnaires were returned by 3271 children (57.3%), of whom 7.4% had WB (6.1% non-severe and 1.3% severe) and 17.2% had MTW (9.4% non-severe and 7.8% severe). Severe disease was more frequent in children with MTW (31.8%) than in those with WB (5.1%). Whereas the prevalence of MTW had increased since 1964, the prevalence of WB had remained stable over this period. After adjustment for confounders, age had no influence on either wheeze type, and male sex was only associated with non-severe WB [OR 1.44, 95% confidence intervals (1.03-2.02)]. In the WB group eczema or/and hay fever in the child were more strongly associated with severe wheeze [OR 3.28(1.49-7.23) vs. OR 1.84(1.31-2.60)]. In the MTW group, this association was noticeably higher than in the WB group, but did not differ much between non-severe and severe wheeze [OR 5.46(3.70-7.20) and OR 6.01(4.1-8.75) respectively]. The presence of any allergic diseases in either parent increased the odds for non-severe and severe MTW at the same level of magnitude [OR 1.92(1.38-2.68) and OR 1.92(1.34-2.76) respectively], and statistically non-significantly for severe WB [OR 1.75(0.78-3.94)]. Living in a deprived area increased both severe WB and severe MTW, reaching statistical significance only for severe MTW [OR 1.96(1.39-2.78)]. Smoking in the house was associated with increased risk of WB and MTW of any severity. WB and MTW differ in prevalence trends and severity. Within severity levels, the influence of age, allergic diseases in children and parents also differed between these two wheezing subtypes.

- Abstract
Numerous surveys of school-aged children have shown increasing asthma prevalence with a less publicized but noticeable change in the male to female ratio. We sought to confirm this change in the sex ratio in four questionnaire-based surveys and investigate possible explanations. Identical questionnaire surveys were performed in 1989 (n=3,390), 1994 (n=4,047), 1999 (n=3,540) and 2004 (n=1,920) in school-children aged 9-11 years. Over these 15 years the male to female ratio (M:F) significantly narrowed for wheeze (1.34 to 0.98:1 P < 0.0002), for asthma (1.74 to 1.02:1 P < 0.0001), for eczema (1.42:1 to 0.81:1 P < 0.0001) and for hay fever (1.46 to 0.93:1 P < 0.0001). The diagnosis of asthma in children with wheeze was more commonly made in boys in 1989 relative risk RR 1.32 (1.12, 1.56), even in those with accompanying eczema and/or hay fever RR 1.20 (0.99, 1.45). By 2004 this sex bias in diagnosis was no longer present, RR 1.01 (0.91, 1.12) for wheeze and 1.02 (0.85, 1.21) for those with wheeze and eczema and/or hay fever. From 1989 to 2004 no significant difference in sex distribution changes between older and younger children occurred, making secular trends in the onset of puberty in females an unlikely contributory factor. The disappearance of the bias to diagnose asthma in symptomatic males but not in females may be partly responsible for the narrowing of the sex ratio, but other factors such as those enhancing the expression of asthma and atopy in females may also be implicated., ((c) 2006 Wiley-Liss, Inc.)
