Risk factors in horses refer to variables or conditions that increase the likelihood of disease, injury, or other adverse health outcomes in equine populations. These factors can be intrinsic, such as age, breed, and genetic predisposition, or extrinsic, including environmental conditions, management practices, and exposure to infectious agents. Understanding risk factors is important for developing preventive strategies and improving health management in horses. This page aggregates peer-reviewed research studies and scholarly articles that explore the identification, assessment, and mitigation of risk factors in equine health, with the aim of enhancing disease prevention and promoting overall well-being in horses.
Webb PA, Monath TP, Reif JS, Smith GC, Kemp GE, Lazuick JS, Walton TE.Epidemiologic evaluations were made of farm personnel on vesicular stomatitis-affected premises along the front range of the Rocky Mountains in Colorado during the 1982 epizootic. A similar antibody prevalence was noted to that of veterinarians and research and regulatory personnel who were involved with the same epizootic. Risk of infection resulted from intimate physical contact with infected horses or cows. Incidence and infection rates in horses were 45%; rates in cows were much lower, only 5%. Some epidemiologic clues were gained by a detailed study of an equine ranch. The pasture was inc...
Reif JS, Webb PA, Monath TP, Emerson JK, Poland JD, Kemp GE, Cholas G.In 1982-1983, an epizootic of vesicular stomatitis occurred in the western United States. Veterinarians, research workers, and regulatory personnel who were exposed to vesicular stomatitis virus were examined for patterns of human infection and prevalence of vesicular stomatitis New Jersey serotype neutralizing antibody. Insight into the mechanism of transmission was sought by comparing activities of antibody-positive and antibody-negative persons. A statistically significant risk factor was a history of infected animals sneezing in the face of serosurvey participants. Elevated odds ratios wer...
Engels M, Nowotny N, Metzler AE, Wyler R, Bürki F.An EHV 1 isolate from the Lippizan Stud at Piber, which caused the abortion and paresis outbreak in 1983, was investigated using 3 known subtype 1 and 2 subtype 2 strains for comparison. Broad-scale restriction enzyme analysis as well as cross-neutralization with hyperimmune sera produced in rabbits were performed, and SDS-PAGE of infected cell proteins was conducted on a limited scale. The Piber isolate was clearly classified as a subtype 1 strain of EHV 1, and showed closest resemblance in its restriction patterns with a British EHV 1 strain, which originated from an outbreak with paretic sy...
Hird DW, Casebolt DB, Carter JD, Pappaioanou M, Hjerpe CA.A case-control study to identify risk factors associated with isolation of Salmonella was accomplished, using data from records of horses hospitalized in the period July 1971 through June 1982. Horses in which nasogastric tubes were passed were at 2.9 times greater risk of having Salmonella isolated, compared with horses that did not undergo this procedure. Horses treated with antibiotics parenterally were at 6.4 times greater risk, and those treated with antibiotics orally and parenterally were at 40.4 times greater risk of developing salmonellosis, compared with horses not receiving such tre...
Bixby-Hammett DM.In brief: In a two-year study of the estimated 13,428,000 hours of horse activities by 18,408 US Pony Clubs (USPC) members aged 6 to 21 in scheduled supervised programs, there were 64 accidents resulting in 88 injuries in 16 areas of the body. The head/face was the area most often injured (27.27%), and bruise/abrasion was the most common type of injury (28.26%). Cross-country riding was the most dangerous event (42.31%). Unexpected actions of the horse caused many accidents-25% occurred when the horse bucked and threw the rider, 23.08% when the horse refused a jump, and 17.31% when the horse f...
Muwanga LC, Dove AF.We report the frequency with which horse riders with a significant head injury present to a large accident and emergency department. We have also recorded details about the use of headwear and conclude that horse-riding is associated with a serious risk of head injury and 'protective' headwear may not always protect.
Hird DW, Pappaioanou M, Smith BP.In an investigation of a 1981-1982 outbreak of nosocomial Salmonella saintpaul infection in hospitalized horses at the University of California Veterinary Medical Teaching Hospital in Davis, California, a case-control study was performed using data gathered from the records of 33 cases and 132 controls. Multiple logistic regression risk analysis was used to identify factors associated with isolation of the organism, controlling for the effects of other, possibly confounding variables. Horses receiving parenteral antibiotics were at 10.9 times greater risk of having S. saintpaul isolated than w...
Pounder DJ.The fatalities associated with the riding and handling of horses in South Australia over the 11-year period 1973-1983 are reviewed. There were 18 deaths, including two sudden natural deaths in the saddle and one drowning. The 15 cases of horse-related trauma represent a death rate of approximately one per million population per annum. Thirteen of the deaths were the result of a head injury after a fall. Nine persons were not wearing protective headgear. The two principal groups at risk were male professional riders with a mean age of 32 years and female amateurs with a mean age of 19 years.
Ilgren EB, Teddy PJ, Vafadis J, Briggs M, Gardiner NG.We present a clinical and pathological study of brain injuries in horse-riding accidents. Among six fatal cases, all experienced riders varying in age and sex, two were not wearing helmets and four had inadequate protective headgear. Among five non-fatal cases, four wore adequate helmets and only one of these suffered permanent neurological damage. The fifth was not wearing a helmet and although he eventually returned to work, a CT scan following the fall showed a deep-seated perithalamic hematoma. These findings are consistent with those of virtually all other studies in that they suggest tha...
Pascoe PJ, McDonell WN, Trim CM, Van Gorder J.A retrospective survey of 300 surgical treatments for colic involving 341 interventions was carried out to determine mortality rates and associated factors. These horses had been referred to the Ontario Veterinary College over the period September 1974 to February 1980. Data from the case records was collected and stored on a computer and statistical analysis was carried out using X(2) tests.Fifty percent (150/300) of the horses survived to be discharged from the hospital. Fifty-two horses were euthanized during the operation and another ten horses should have been; if these cases are excluded...
Bernhang AM, Winslett G.In brief: It has always been assumed that participants in equestrian sports are at high risk of serious injury and that minor injuries are common. This study of American Horse Shows Association and United States Pony Clubs horse shows tried to determine if shows are as safe as or safer than other sports, what the accident rate is for horse shows, if any factors influence the accident rate, and what types of accidents and injuries occur. There were 290 reported injuries and two deaths in the 984 responding shows. The accident rate per entry was 0.0003. There was no statistically significant rel...
Coldman AJ, Elwood JM, Gallagher RP.The relationship of testicular seminoma with several factors was explored using a case-control study. Previously recognized associations with cryptorchidism and infantile inguinal hernia were confirmed and relationships were also found with cycling and horse-riding. These findings represent the first relationships of testicular cancer with well-defined postnatal risk factors.
Naylor JM, Kenyon SJ.Horses were deprived of food but not water for a period of five days. There was a progressive decrease in circulating lymphocyte count and compromised host deference. In vitro phagocytosis of yeast fell from a mean of 97 per cent in fed horses to 78 per cent in horses deprived of food for five days. The Arthus response to intradermal challenge with allergens fell to 57 per cent of fed values. These changes indicated that food deprivation increases the susceptibility to bacterial infections; persistent anorexia in chronic bacterial infections may limit the horse's ability to cast off infection....
Nyaga PN, Wiggins AD, Priester WA.Three hundred and sixty cases of diagnosed equine influenza reported to the Veterinary
Medical Data Program (VMDP) of the National Cancer Institute, U.S.A., were tested for the
independent effects of age, breed and sex, relative to a reference clinic-hospital population of 84,562
equine patients. Horses of age category 2-6 months showed a significant risk above unity for
infection with equine influenza virus whereas, horses in age category 7-10 yr showed a significant,
low and sparing risk. Horses under two months or over 10 years, as well as those in ages from 6
months to 7 yr had non-s...
McPherson EA, Lawson GH, Murphy JR, Nicholson JM, Breeze RG, Pirie HM.Breed, age, weight, type of work performed, seasonal onset, poor ventilation and exposure to moulds in the habitat were investigated in relation to the occurrence of chronic obstructive pulmonary disease (COPD). COPD was most commonly detected in showjumping and hacking horses. The older a horse, the more likely it was to become affected although most were 6 to 10 years of age. Of the horses in this sample of the population, which was not a random one, thoroughbred horses were affected least and ponies most often. The high incidence in ponies was related to their more frequent exposure to poor...
Ackerman N, Johnson JH, Dorn CR.In a retrospective study, 74 horses met defined historical and clinical features indicative of navicular disease. Most of the affected horses were 4 to 9 years old. Males had a greater risk of navicular disease than females, geldings had a greater risk than stallions, and Quarter Horses had a greater risk than other breeds. Diagnostic radiographic changes were found in 42 of 70 horses examined. The distribution of diagnostic radiographic changes between the right and left fron feet was equal. There was no correlation between the finding of diagnostic radiographic changes and the horse's respon...
Dorn CR, Priester WA.Four hundred sixty-nine oral-pharyngeal malignancies diagnosed in dogs, cats, horses, and cattle and submitted to the Viterinary Medical Data Program between March 1, 1964, and Dec 31, 1974, were analyzed. Of these cases, 84% were in dogs. The most frequent oral-pharyngeal cancer in dogs was melanoma; in cats and horses, it was squamous cell carcinoma. In dogs, the risk of developing melanoma increased more with age than did the risk of developing squamous cell carcinoma and fibrosarcoma. Male dogs had significantly greater risk of developing fibrosarcomas and melanomas than did female dogs. T...

Dorn CR, Garner HE, Coffman JR, Hahn AW, Tritschler LG.The characteristics of a series of equine laminitis cases were compared with that of other Equidae examined at the University of Missouri Veterinary Hospital and Clinic during May, 1965 through December, 1971. The model age for ponies with laminitis was 7-9 years and for all other cases the model age was 4-6 years. Also the predominant age for mares was 4-6 years and for males was 7-9 years. After controlling for age and breed differences, there were significantly fewer castrated males among the affected males than expected (P small than 0.02), indicating that hormonal factors may play a role ...
Mojsiejczuk L, Whitlock F, Chen H, Magill C, Aranday-Cortes E, Bone J, Tong L, Da Silva Filipe A, Bryant N, Newton JR, Chambers TM, Reedy SE....Influenza A viruses (IAVs) are prime examples of emerging viruses in humans and animals. IAV circulation in domestic animals poses a pandemic risk as it provides new opportunities for zoonotic infections. The recent emergence of H5N1 IAV in cows and subsequent spread over multiple states within the USA, together with reports of spillover infections in humans, cats and mice highlight this issue. The horse is a domestic animal in which an avian-origin IAV lineage has been circulating for >60 years. In 2018/19, a Florida Clade 1 (FC1) virus triggered one of the largest epizootics recorded in the ...
Pinho APVB, Ferreira F, Fuck JJ, de Oliveira JP, Dias RA, Grisi-Filho JHH, Heinemann MB, Telles EO, Amaku M, Ferreira Neto JS.Considering that control strategies for Equine Infectious Anemia, based on the serological diagnosis of equids and the removal of positive animals, may not be optimal for developing countries with an absolute predominance of grade working animals, this study aimed to address this issue based on the epidemiological situation of the disease in Pará, a state in the Brazilian Amazon. Pará was divided into five regions, and within each region a pre-established number of farms were randomly selected. Within each farm, a pre-set number of animals were randomly selected and submitted to Agar Gel Imm...
da Silva VV, de Sá Barreto Maia Leite DP, de Crasto Souza Carvalho Reis J, de Almeida Braz BM, Junior JWP, de Almeida JC, Mota RA.This study identifies high-risk areas for Equine Infectious Anemia (EIA) in Brazil and analyzes the temporal trend of the disease across regions and Federative Units over an 18-year period (2006-2023), using data from the National Animal Health Information System (SIZ). During the analyzed period, 111,826 cases of EIA were reported in Brazil, with a predominance in the Northeast (39.75 %), Central-West (27.56 %), and North (20.95 %) regions. The state of Mato Grosso recorded the highest number of cases (17.02 %), while Sergipe had the lowest (0.36 %). In the incidence risk analysis, the s...
Chapman M, Fenner K, Thomas MJW.Equestrianism has an opportunity to learn lessons relating to safer human-horse interactions from those who no longer have a voice, by drawing data from the investigation of horse-related human fatalities and participating in accident analysis. Many human-horse related injuries and fatalities are not examined in equestrianism for the purpose of developing safer future risk mitigation practice, often due to the philosophy that horse sport is simply dangerous. This study analysed data from the Australian National Coronial Information System (NCIS) relating to fatalities involving human-horse int...
Gould S, Roy IR, Gabriel FD, Lowe R, Lin CY.Equestrian sports are associated with high rates of major injury compared to collision and powered two-wheel sports. Advancements in rider and horse safety equipment and the implementation of comprehensive emergency action planning standards may help mitigate injuries, particularly in regard to the Olympic disciplines of dressage, show jumping, and three-day eventing covered in this review. Personal safety equipment to consider includes helmets, safety and air vests, and horse tack including safety stirrups, acoustic dampeners, and breakaway reins. Equestrian event medical coverage requires em...
Chapman M, Fenner K, Thomas MJW, Thompson K.With the growth of the equestrian industry, risk exposure and the obligation to maintain the health, safety, and welfare of humans and horses remain front and centre. As there has been no apparent reduction in non-fatal human horse-related injuries, we asked industry stakeholders to discuss their current management and risk mitigation practices and highlight potential barriers to improving these processes. Semi-structured interviews were conducted with 20 stakeholders from Australian equestrian work- ( = 9) and non-work- ( = 11) related organisations to determine the potential benefits and fea...
Neville EK, Neville CC, Hicks H.The size, strength, and unpredictability of horses, makes any interaction a potential situation for minor to severe injury. Despite this, horses continue to be popular for work and recreational activities. There have been five recent Australian publications that have examined various aspects of horse-related trauma, but none have been conducted in regional New South Wales (NSW). This study aims to report on the pattern of horse-related trauma that met the Institute of Trauma Injury Management's (ITIM) Trauma Registry criteria for people who presented to the emergency department at a regional N...
Muñoz-Caro T, Gavilán P, Villanueva J, Oberg C, Herrera C, Fonseca-Salamanca F, Hidalgo A.Parasitic infections are among the most important causes of morbidity and mortality in horses worldwide. In the Andean mountainous regions of Chile, horses are a highly valued specie, playing a key role as working animals also providing support in cattle transhumance grazing into high mountainous areas during dry season. The breeding and maintenance of horses in the mountainous region of La Araucanía in Chile is a key issue allowing to the subsistence economy of communities with a strong ethnic component represented by Mapuche-Pehuenche origin families. However, the health status of these ani...
Bartlett E, Blackwell EJ, Cameron LJ, Hockenhull J.The way horses are trained has implications for equine welfare and training success, yet little is known about the factors that influence horse-owners' choice of training approach (TA). Limited understanding in this area will hinder the development and dissemination of evidence-based training advice to owners. Consequently, this study aims to identify demographic and attitudinal factors that influence horse-owner TA selection. A 22-question online survey collected information from 1,593 horse-owners about their demographics, equestrian activities, goals and beliefs. Participants rated how like...

Christofi E, Hoopes J, El-Hage C, Coffin J, Riley T, Cumming B.Since their arrival in the 1700s, horses have played a significant role in shaping the identity of rural and remote communities. However, Indigenous perspectives on the historical role of horses in communities have been largely underrepresented. In remote regions, where access to veterinary and medical services is limited, interactions between people and free-roaming horses present a potential risk for zoonotic disease transmission. This review identifies potential pathways for the transmission of equine zoonoses in rural and remote Aboriginal and Torres Strait Islander communities, aiming to ...
Bazan L, Argibay HD, Borges-Silva W, Pita Gondim LF, Dos Santos Mattos TA, Santana JO, da Silva EM, Begon M, Khalil H, Costa F, de Oliveira Carneiro I.Toxoplasma gondii is a globally neglected zoonotic parasite, particularly prevalent in socioeconomically vulnerable areas. Various animal species serve as reservoirs for T. gondii across different regions, including domestic cats, livestock, and a variety of wild and synanthropic animals. In urban areas, especially informal settlements, the close coexistence of humans, domestic animals, and wildlife may influence local transmission dynamics. This study evaluated the seroprevalence and associated risk factors for T. gondii infection in domestic and synanthropic animals from two low-income neigh...
Kern-Allely C, Scott D, Magzamen S, Duncan C.Air pollution is a major global health threat that is expected to worsen, yet its effects on domestic animals remain poorly understood.

Ritter B, Dastagir N, Tamulevicius M, Bucher F, Obed D, Vogt PM, Dastagir K.Hand injuries are frequently caused by sports and are associated with long periods of inability to work and high economic health costs. After ball sports and cycling, the most common cause of hand injuries is horseback riding. Therefore, measures should be taken to prevent these risks and increase safety in sports, however data characterizing equestrian sports-associated injuries are limited. Methods: A retrospective monocentric cohort study was performed including 39 patients (mean age: 35 ± 2.6 (range 9-65) years, female 89.7% who sustained an injury to the hand while practicing equestr...
Cuervo-Arango J, Stout TAE, Claes AN.This retrospective study compared the relationship between embryonic vesicle diameter at first pregnancy diagnosis and early embryonic loss (EEL) across three pregnancy types: artificially inseminated broodmares (AI; n = 263), recipients carrying in vivo-derived flushed embryos (IVD-F; n = 312), and recipients carrying in vitro-produced embryos by intracytoplasmic sperm injection (IVP-ICSI; n = 161). Vesicle diameter was recorded at Day 12 post-ovulation in AI, Day 4 post-embryo transfer (ET) for IVD-F, and Day 7 post-ET for IVP-ICSI pregnancies. Mean (±SD) vesicle diameters and E...
Kuwano A, Kusano K, Mita H, Tamura N, Tokushige H, Iimori M, Kurimoto S, Kawabata M, Ueno M, Okada Y, Kamiya K, Tanaka K.Pathological hoof-wall cavities unrelated to nailing (so called "Gidoh" in Japan) often occur in the feet of horses. In 2001, in facilities managed by the Japan Racing Association (JRA), Gidoh was found to occur most frequently in the toe of the fore-hoof, with no gender predilection, and was more prevalent in older horses. However, it remains unclear whether this trend has continued in recent years, which pathological type of Gidoh predominates, and whether there are differences in prevalence among seasons. Therefore, in spring (April) and autumn (October) of 2020, we surveyed all racehorses ...
