Arbetsbelastning vid städning av hotellrum
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Enligt Arbetsmiljöverkets rapport ”Arbetsmiljön 2013” har 40 procent av alla hotell- och kontorsstädare ont i nacke, rygg, axlar eller armar varje vecka. 60 procent av dem känner sig uttröttade i kroppen. Arbets- och miljömedicin (AMM) Syd har tagit fram åtgärdsnivåer för ett antal belastningsmått, ”AMM Syds åtgärdsnivåer för ergonomisk belastning”, och om man överstiger dessa, anser vi att risken för belastningsskada är stor. Vi har studerat hotellrumsstädares belastning och jämfört med våra åtgärdsnivåer.Vi mätte den fysiska arbetsbelastningen hos fjorton kvinnliga hotellrumsstädare under en vanlig arbetsdag, på en deltagare åt gången. De arbetade på sju olika hotell i södra Sverige. Några var anställda av städföretag och några direkt av hotellen.Vi fann att hotellrumsstädare har en väldigt hög arbetsbelastning i övre delen av kroppen, både vad gäller rörelsehastighet, arbetsställningar och muskelansträngning (se Tabell på sid 3). Samtliga deltagare hade för hög rörelsehastighet i överarm och handled och för lite vila i underarmens muskler i jämförelse med våra åtgärdsnivåer. Även vad gäller framåtböjningen av huvudet, överarmens arbetsställning och underarmens muskelbelastning fann vi för höga nivåer. Hotellrumsstädning överskrider nio av våra elva åtgärdsnivåer för ergonomisk belastning. Detta betyder att hotellrumsstädare har en väldigt hög risk att drabbas av belastningsskador.RekommendationerFör att minska risken för belastningsskador bland hotellrumsstädare måste arbetstempot sänkas, genom att minska antalet rum som ingår i en hotellrumsstädares arbetsdag.Personalen bör erbjudas regelbundna medicinska kontroller avseende ergonomiskt belastande arbete så att man tidigt sätter in åtgärder för den arbetstagare eller grupp av arbetstagare som är på väg att utveckla skada i muskler och/eller leder. Arbetsplatsen rekommenderas att ha företagshälsovård knuten till sig, som kan genomföra de medicinska kontrollerna och som kontinuerligt gör riskbedömningar av arbetet. De bör också ha som uppgift att utbilda städpersonalen i ergonomi.

- Purpose. This study aimed to investigate the effects of using hand grip or resisted wrist extension as the reference contraction, and two electrode positions, on field recordings of forearm extensor muscle activity. Materials and methods. Right forearm extensor muscle activity was recorded using two electrode pairs (over the most prominent part (position 2) and proximal to that (position 1)) during one working day in 13 female hotel housekeepers. Each subject performed the two maximal voluntary contractions (MVCs), and the electrical activity obtained during these (maximal voluntary electrical activity (MVE)) was used for normalization. Each set of recordings was analysed twice, once using hand grip as the MVC and once using resisted wrist extension. Results. Resisted wrist extension showed a higher group mean MVE than hand grip. Position 2 had higher correlation between MVE and force during the MVCs. The workload during cleaning was lower when using resisted wrist extension as reference than when using hand grip (24%MVE vs 46%MVE; p = 0.002 at position 2) for the 90th percentile. The workload (99th percentile) was overestimated in two subjects when using hand grip as reference. Conclusions. Problems associated with poorly activated forearm extensors can be overcome by using resisted wrist extension as reference.

- IMPORTANCE Supplementing preterm infants with long-chain polyunsaturated fatty acids (LC-PUFA) has been inconsistent in reducing the severity and incidence of retinopathy of prematurity (ROP). Furthermore, few studies have measured the long-term serum lipid levels after supplementation. OBJECTIVE To assess whether ROP severity is associated with serum levels of LC-PUFA, especially docosahexaenoic acid (DHA) and arachidonic acid (AA), during the first 28 postnatal days. DESIGN, SETTING, AND PARTICIPANTS This cohort study analyzed the Mega Donna Mega study, a randomized clinical trial that provided enteral fatty acid supplementation at 3 neonatal intensive care units in Sweden. Infants included in this cohort study were born at a gestational age of less than 28 weeks between December 20, 2016, and August 6, 2019. MAIN OUTCOMES AND MEASURES Severity of ROP was classified as no ROP, mild or moderate ROP (stage 1-2), or severe ROP (stage 3 and type 1). Serum phospholipid fatty acids were measured through gas chromatography-mass spectrometry. Ordinal logistic regression, with a description of unadjusted odds ratio (OR) as well as gestational age- and birth weight-adjusted ORs and 95% CIs, was used. Areas under the curve were used to calculate mean daily levels of fatty acids during postnatal days 1 to 28. Blood samples were obtained at the postnatal ages of 1, 3, 7, 14, and 28 days. RESULTS A total of 175 infants were included in analysis. Of these infants, 99 were boys (56.6%); the median (IQR) gestational age was 25 weeks 5 days (24 weeks 3 days to 26 weeks 6 days), and the median (IQR) birth weight was 785 (650-945) grams. A higher DHA proportion was seen in infants with no ROP compared with those with mild or moderate ROP or severe ROP (OR per 0.5-molar percentage increase, 0.49 [95% CI, 0.36-0.68]; gestational age- and birth weight-adjusted OR, 0.66 [95% CI, 0.46-0.93]). The corresponding adjusted OR for AA levels per 1-molar percentage increase was 0.83 (95% CI, 0.66-1.05). The association between DHA levels and ROP severity appeared only in infants with sufficient AA levels, suggesting that a mean daily minimum level of 7.8 to 8.3 molar percentage of AA was necessary for a detectable association between DHA level and less severe ROP. CONCLUSIONS AND RELEVANCE This cohort study found that higher mean daily serum levels of DHA during the first 28 postnatal days were associated with less severe ROP even after adjustment for known risk factors, but only in infants with sufficiently high AA levels. Further studies are needed to identify LC-PUFA supplementation strategies that may prevent ROP and other morbidities.

Current status of the equine sector in the central Baltic region (Finland, Latvia and Sweden)
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report covers basic descriptions and characteristics of the equine sector, including statistics on number of horses, horse farms, employment, current structure and recent dynamics in the horse sector in Finland, Latvia and Sweden and also the mobility (e.g. trade, import, export and tourism) within the Central Baltic Region. The information was gathered through literature reviews, round table discussions and interviews with equine organisations and stakeholders, and through visits to farms with equine business activities in each of the three countries. Horses in Finland, Latvia and Sweden At the moment the horse population in Finland is growing steadily. In 2010 there were about 75 000 horses. Most of these are warm-blooded trotting horses, but riding horses are becoming increasingly popular as riding as a hobby increases in popularity. Approximately 35 000 people own at least one horse and co-ownership is becoming a common way of owning a horse with relatively small costs and responsibilities, especially among trotting sports. There are approximately 16 000 stables, of which over 3 000 are business orientated. These numbers are still only estimates, because Finland is lacking a comprehensive register of stables and stable enterprises. Although statistical data on the number of horses, breeds, herds, stables etc. are being collected and are available in Latvia, there is still a lack of statistical data that characterise the sector in relation to employment, provide an idea of the financial results, and characterise horse uses for tourism or therapy purposes. For example, there are no data on the number of people working with horses. This is perhaps related to the perception of the sector as being located within the context of horse breeding. Statistical data show that the number of horses in Latvia in general has decreased, from 15 250 in 2005 to 11 476 in 2012, and the current trends indicate that it could decrease even more. The number of livestock has decreased correspondingly, from 9814 in 2005 to 5577 in 2012. More than 84% of all farms have 1 to 5 horses, and only a few farms have more than 100 horses. The number of horses in Sweden decreased in the early 1920s from about 700 000 to about 70 000 in the 1970s. During the past 30 years the number of horses has increased tremendously, but the trend seems to be stagnated the last few years. Today there are approximately 362 700 horses and about 20% of all horses in Sweden are within business establishments. The number of horses per 1 000 habitants is 39 for the whole country and Sweden is now estimated to have the second highest density of horses per capita in Europe. There are approximately 77 800 establishments involving horses in Sweden. The equine businesses have on average 4.7 horses and provide full-time or part-time work for a total of 25 000 people. About two-thirds of those working with horses are women. Horse related legislation in Finland, Latvia and Sweden Environmental legislation is one of the broadest judicial systems in Finland. It consists of a number of different laws and regulations, relating to waste disposal, water protection, environmental protection, land use and construction. After EU membership, environmental legislation in Finland was harmonised with EC (European Community) legislation, especially in the case of environmental protection and conservation. The main environmental legislation concerning the horse sector in Finland consists of following laws, directives and regulations: 1) Environmental protection law and regulation, 2) Waste law and regulation, 3) EU waste incineration directive, 4) By-product regulation, 5) Nitrate regulation, 6) Law concerning dead animals in remote areas, 7) The law on processing household water in remote areas, 8) Health protection law and regulation, 9) Fertilizer law, 10) Conservation law, 11) Land use and construction law and 12) Law about neighbourliness. According to the requirements of the Ministry of Agriculture, the policy of the horse breeding sector in Latvia is based on: a) Horse breeding is performed according to the targets stated in the breeding programme, which are based on production of high quality animals, preservation and improvement of the genotype through purposeful use of the breeding stock and improvement of horse monitoring, b) The importance of the development of horses and equestrian sports within the framework of the common agricultural policy is emphasised in order to encourage development of the rural environment, and c) Horse breeding is compliant with welfare regulations. National and European Union aid for the development of the agricultural sector is allocated to horse breeding too. Most of it consists of aid for breeding measures in the equine sector. Currently there are no specific regulations in Latvia which define requirements for keeping horses. Horse breeding is not distinguished separately within the field of animal welfare in Latvia and therefore the main document is the Animal Protection Law. Its norms are general, while Cabinet Regulation No 959 ´Welfare Requirements for the Keeping and Training of Sport, Work and Exhibition Animals and Use Thereof in Competitions, Work or Exhibitions´ does not specify actions with horses and can easily be interpreted in different ways. There is no measurable evaluation system to assess fulfilment of the requirements in the Cabinet Regulations. The law stipulates the actions and activities which may be undertaken with an animal and those which are strictly forbidden and lists the institutions that should supervise compliance with the law and the welfare requirements. Latvia lacks the basis of normative documents that would specifically regulate personal safety in the horse breeding sector and in businesses related to horse use. Therefore the common normative basis has to be considered, the foundation of which is the ´Labour Protection Law´. The foundation of Swedish environmental legislation is the Swedish Environmental Code. The purpose of the Swedish Environmental Code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. The Code is a legislative framework based on a number of fundamental principles permeating international environmental protection and resource management. These include the "precautionary" principle, the "polluter pays" principle, the "product choice" principle and principles governing resource management, natural cycles and appropriate siting of industrial (and other) operations and remedial measures. The main environmental legislation in Sweden concerning the horse sector consists of the following laws, directives, ordinances and regulations: 1) Environmental Code, 2) Ordinance concerning environmentally hazardous activities and the protection of public health, 3) Ordinance on environmental consideration in agriculture, 4) Nitrate directive, 5) Water directive, 6) Swedish guidance on storage and spreading of manure, 7) Regulation on environmental consideration in agriculture as regards plant nutrients, 8) Ordinance on inspection and enforcement according to the Environmental Code, 9) Ordinance on self-inspection by operators, 10) Ordinance on animal by-products, 11) Ordinance on fees for examination and supervision under the Environmental Code and the fees ordinance, 12) Regulations on the protection of the environment, in particular the soil, when sewage sludge is used in agriculture, 13) Regulations on consideration for natural and cultural values in agriculture, 14) Ordinance on environmental penalty charge, 15) The Planning and Building Ordinance, 16) The Land Code. In Sweden the occupational safety and health issues in general are regulated in the Work Environmental Act (SFS 1977:1160), in the Work Environmental Ordinance (SFS 1977:1166) and in several provisions. There is no specific legislation regarding occupational health and safety in the horse sector. However, these issues are included in the provision Working with animals (SFS 2008:17). Some results of the round table discussions in Finland, Latvia and Sweden In general, the participants in round table discussions in Finland were hoping for concrete solutions and examples of low-cost and easy help for everyday businesses. Entrepreneurs with lower profitability need more support, but the challenge is to get them involved in education or advisory events. The riding sector at least is much divided, with some businesses having as many customers as they can serve, and others who are constantly on the edge of bankruptcy. To help those small and medium-sized enterprises that need help the most, the project should produce advice that can immediately be used in practice, and concrete results and solutions. The problem with small and medium-sized businesses is the lack of capital and the related impossibility of investing large amounts of money in new technologies or large-scale facilities. In this sector the profitability and competitiveness are often low, but small changes in operations could improve these. Many business owners are still lacking business skills and they may not see what they could use as a competitive advantage. The current understanding of the equine sector in Latvia has to be reconsidered or a better understanding has to be created. Therefore the policy guidelines and the aid to the sector will have to be reviewed. For example, according to the view of the Ministry of Agriculture of the Republic of Latvia, the equine sector only concerns breeding and accordingly state aid is predominantly provided for this purpose. The Latvian Horse Breeding Association also considers breeding to be its priority, but several representatives of the tourism industry expressed the opinion that horse breeding should be reconsidered, paying special attention to the Latvian horse breed, which could be interesting for foreign and local tourists as a special feature of

- BACKGROUND: Musculoskeletal disorders (MSDs) are a common reason for health problems and sick leave in many professions. A work arena where MSDs have not been sufficiently studied is stable work. Here many heavy and repetitive work tasks are performed manually with old-fashioned working tools.OBJECTIVE: The aim of this study was to use an analytical approach to identify, evaluate and grade ergonomic problems in physical work performed during daily activities in horse stables and relate these to MSDs among the workers and to the design of the tools.METHODS: Three common work tasks were studied to identify, evaluate and grade ergonomic problems; mucking out, sweeping and bedding replacement. Used methods were Hierarchical Task Analysis, Heuristic Evaluation and Rapid Entire Body Assessment.RESULTS: Several high-risk operations were found in mucking out boxes and disposal of bedding material. The problems consisted of awkward working postures such as a twisted and bent back, arms in an elevated position, wrists in extreme joint positions and handling of heavy loads.CONCLUSIONS: By using an analytical approach it is possible to identify presumptive ergonomic problems without extensive empirical research. In most high-risk operations, long-shafted tools or a wheelbarrow were used, which emphasize a need to develop tools with better ergonomic design to improve the working situation. The limitation is that the ergonomics problems found are not finally validated. The results show where deeper empirical research is needed, both regarding how MSDs occur and how tools and environment contribute to physical problems.
